Thanks! Bad news - can you build stellarium from source code in debug mode and run it through gdb?

gzotti (georg-zotti) wrote :

EXT_gpu_shader4 MISSING!

This test result may indicate that the GPU driver reporting GLSL1.3 is not enough. We do not have enough samples yet, but https://en.wikipedia.org/wiki/OpenGL#OpenGL_3.0 indicates this extension is essential, therefore we test for it explicitly at least in the -d test.

Did any previous version of Stellarium (0.13 or later) run on this system? The processor graphics is reported to support Intel HD (OpenGL4?) on Windows, but I don't know capabilities of BSD Mesa GPU drivers.

I'm using on the identical hardware (Acer C720) and the same version of FreeBSD (r292778) the stellarium version 0.14.1 whichout any crash; a log.txt of -d is attached; please let me know if I should recompile 0.14.3 with any additional (debug) flags or with gcc option -g to gather a bt in gdb;

Alexey Dokuchaev (danfe) wrote :

Can you show us your C[XX]FLAGS? Perhaps your CPU does not support some instruction(s) that compiler is generating due to presence of -march=<wrong-cpu> or even -march=native. Version 0.14.1's code might not trigger this particular code generation logic (optimization) in the compiler.

You might also want to set -O0 to disable all optimizations, or try GCC instead of Clang (default compiler on contemporary FreeBSD versions) and see if it changes anything.

I'm attaching the log file of the build with clang; and the build with gcc and -O0; with the latter stellarium crashes without saying any line;

I checked the build log of poudriere for the port astro/stellarium; poudriere installs into the build jail 117 existing other packages (see the list below); I will remove them all to force poudriere to rebuild them and it dependencies with -g and without strip the binaries; maybe this will get us a backtrace with better information:

I'm attaching a photo taken in the moment short before the crash to show how far the GUI went; in the left upper part of the display is already a small window, knowing the position Paris; it crashes before going fullscreen.

Alexander Wolf (alexwolf) wrote :

Please try set video/fullscreen = false in ~/.stellarium/config.ini and check it again.

Matthias Apitz (gubu) wrote :

Setting fullscreen = false does not avoid the crash, only the target window for resizing the small one in the left upper part now has a frame and title bar.

I recompiled some 120 packages with debug info, forced installed them, copied the stellarium sources in place and can set a break point in main, list etc. but when I let it run the bt after the crash does not show any function names;

there was a hint in freebsd-ports@ about mixture of clang's libc++.so and gcc's libstdc++.so but only libc++ is loaded as ldd shows;

Re/ the backtrace: I forgot that stellarium is threaded and I have to use "thread apply all bt" to get the bt; now attached;

astro/stellarium port on FreeBSD has been updated to version 0.15.0_1 - please check it.

Matthias Apitz (gubu) wrote :

I've checked this already on the weekend, but only updated this singular port to 0.15.0_1. I was even surprised that it compiled against all other ports in that jail with a tree being from 1st of May. I started yesterday in a new jail the compilation of all ports based on SVN head of August 6. The will take a few more days and I will report back.

Matthias Apitz (gubu) wrote :

I have updated the complete system to ports from head as of August 6, which brings among others stellarium 0.15.0_1; the crash remains the same with the same symtoms: the GUI comes up as a small window in the upper right corner, than it crashes;

Matthias Apitz (gubu) wrote :

I have built a memstick with 12-CURRENT (r303343) and installed into it the packages pkg, xorg, kde and stellarium (and all its ~800 dependencies) of a ports build of July 16 (r418627), stellarium is 0.14.3 at this level; the memstick works nice on my Dell Latitude E6330 and Acer C720; on the Dell stellarium works fine, on the Acer C720 it crashes with the known simptoms: it starts and when it will bring the GUI to full screen, it crashes.

It's weird. FreeBSD has a specific key for compiler (see -pthread in cmake script). Could you attach output data from 'ldd stellarium'?

(This is copy-paste of that code you quited run through as(1)). I'd like to know which file this SIMD code comes from. Let's pick the last line above (just as example, you might want to adjust it) and do some grepping.

First, quick sanity check that core dump itself contains this code (it should):

$ perl -e 'open(F, "<:raw", $ARGV[0]) or die $! ; while(<F>) { if (/\x66\x0f\x6e\xa4\x87\x08\x01/) { print "found ($ARGV[0])\n"; exit; } }' stellarium.core

If it does not print "found (stellarium.core)" then I screwed up somewhere or need more information.

If it does, then we can try to find which executable file or library contains this code:

$ perl -e 'open(F, "<:raw", $ARGV[0]) or die $! ; while(<F>) { if (/\x66\x0f\x6e\xa4\x87\x08\x01/) { print "found ($ARGV[0])\n"; exit; } }' /usr/local/bin/stellarium

$ find /usr/local/lib /usr/lib /lib -type f -exec perl -e 'open(F, "<:raw", $ARGV[0]) or die $! ; while(<F>) { if (/\x66\x0f\x6e\xa4\x87\x08\x01/) { print "found ($ARGV[0])\n"; exit; } }' '{}' \;

Note that the last command will most likely take considerable amount of time to run since we're using not the most efficient binary string search here.

i.e. the code is found it the stellarium.core, but not in the executeable and
not in the shared libs;

Does stellarium uses dlopen(3C) to load additional shared libs?

I did in addition with the libs from the ldd output:

I will do this later; as well I will run the perl-grep over the night
over all files below /usr; I have somehow the feeling that the code is
loaded, but not as a shared lib, somehow otherwise from another file...

OK, sounds like a plan. One thing you might want to do is instead of grepping for "movd 0x108(%rdi,%rax,4),%xmm4" (that is, 66 0f 6e a4 87 08 01), grep for actual opcodes of the faulty instruction (I originally did not use it because I didn't know exact opcode string, but "disas /r" from new gdb should give you both the opcodes and mnemonics).

we need a better plan :-(

the grepping does not get any hits (apart of the core file);

launching stellarium below GDB (anyway if gdb or gdb7121) just hangs
where normally the crash occurs; maybe some resource problem;

I'm open for new plans/ideas;

Not sure if I understand you correctly here. Do you mean that it's not possible to do the test I asked for in comment #33?

gives someting like 'not in function'

the 'r' command starts stellarium, splash appears, small GUI window in
left upper corner of display; then it hangs and I have to kill the gdb
proc.

> $ disas /r 0x000000080159472b

could not be done due to hanging/killed gbd session

Apart from memory corruption, it also could be that Stellarium ends up executing wrong memory for some reason. Can you mount linprocfs(5) and "cat /compat/linux/proc/<stellaium-pid>/maps"?

I will attach the file 'maps' of this script:

# cat launch.sh

work/stellarium-0.15.1/src/stellarium &

while true; do
    cat /compat/linux/proc/$!/maps >> maps
    echo MAPS >> maps
done

which catches the maps during the live of the proc.

OK, that explains why faulty code was not found in programs or libraries on disk. This memory is allocated and populated during execution. But it also means that it should not be executed at all. The map dump shows that 0x000000080159a72b belongs to this region:

> 0000000801563000-00000008015fd000 rw-p 0009c000 00:00 0

And it is indeed not executable. Something fishy is going on, and I have no ideas for the moment, except these two:

1. It seems that you're running programs with Spanish locale (es_ES)? Can you try with LANG=C or LC_ALL=C, just to rule this particular peculiarity out? You might try other languages as well, but make sure the setting does get applied.

2. The crash occurs with both splash screen and main window visible at the same time; and the closest function call to Stellarium itself that I can see in the backtrace is QSplashScreen::finish(). Why don't you try to disable all splash-related code in main.cpp at all, starting from line 166: QPixmap pixmap(StelFileMgr::findFile("data/splash.png")); and up to line 367: splash.finish(&mainWin); and see what happens.

I set LANG=C and disabled in the source the splash screen; I removed the

I glanced through the src/*/*.cpp and see a lot of calls to qDebug() ...
how can I activate this to get the messages into a file or stderr?
Where is the impementation of this method or is it part of the Qt lib?

Alexey Dokuchaev (danfe) wrote :

Some more ideas, from most to least probable:

1. We're dealing with some kind of stack corruption, e.g. because large object (or large number of objects) is allocated on stack, or local buffer gets overrun, destroying return address and we end up trying to resume execution from wrong memory.

2. Can you try to restart X11 server with VESA backend (slow) and see if it changes anything?

3. Faulty memory. You might try replacing RAM sticks (unless they're soldered) or run memtest86+ (e.g. from a live bootable CD as I recall FreeBSD port is broken on amd64).

qDebug() messages appear in the log when Stellarium is launched with -d or --verbose options.

with the above changes, it does not crash anymore, but also does not
show any window; does this ring some bell?

The Acer C720 run all in VESA mode because the Haswell is not yet supported in FreeBSD.

I know three C720, all with the same crash in stellarium; this deletes
this option number 3, I think;

I have installed the same (binaries) of the software, same kernel
r314251 and same set of pre-compiled packages (based on port as of March
4, 2017) in an amd64 VM. The Xorg server was tested as 'vesa' and as 'vmware'.
In both stellarium starts fine.

I ssh'ed from another laptop (runs r302904 from July last year and
packages from ports August) to the C720 in question with '-Y' to tunnel
back the DISPLAY. The started stellarium on the C720 crashes at the
same point, i.e. the problem does not depend on the used Xorg server.

Matthias Apitz (gubu) wrote :

I have just made the following comment in the issue we have open as well in FreeBSD bugs tracker https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211758

1)
I own a bunch of laptops Dell E6330 and netbooks Acer C720, they all run the same binary software (kernel and ports compiled on my poudriere oven, a Dell PowerEdge R210), all 12-CURRENT r314251 and packages compiled from ports r435425 (March 4, 2017). On the Dell 6330 the stellarium 0.15.1 runs fine, while the same binary crashes on all Acer C720, always at the same place (when bringing up the GUI after splash screen).

2)
The same binary system+ports is installed at work in Vbox on a Win7 host, using the same Xorg + vboxvideo driver. As well here stellarium works fine.

3)
This let me think, that the issue is related to the video stack in the C720 (Xorg with vesa driver); the Dell 6330 uses same Xorg with intel driver;

4)
With the recent update of all my systems to r314251+r435425 another application with heavy GUI, the ports/games//flightgear, shows now the same problem: works fine on Dell 6330, crashes on Acer C720 when bringing up the GUI after splash;

Matthias Apitz (gubu) wrote :

I've updated one of the Acer C720 to the most recent graphic work kernel
for FreeBSD from https://github.com/freebsd/freebsd-base-graphics
which does allow to use the video-intel driver for Xorg. stellarium
still crashed with the same symptoms while getting the GUI up, until I
realized that the user must be in the group 'video' to have access to
the files below /dev/dri:

crw-rw---- 1 root video 0x6c 9 Apr. 12:57 card0
crw-rw---- 1 root video 0x6b 9 Apr. 12:57 controlD64

Adding the user to the group 'video' makes it finally work fine (also
flightgear works too).

On the other C720 system I still have to use the vesa driver for Xorg and
there are no files or dir /dev/dri. This would explain why stellarium
crashes there, but would not explain how it worked this way in the past.
