Segmentation Fault when trying to start structure-synth

[Mario César Señoranis]

Binary package hint: structure-synth

Trying to start structure-synth, raises a segmentation fault, Every time with any option, I install it from the Software Center, on a Fresh Ubuntu 10.04 Installation.

My laptop is hp530, with an Intel graphic chip, 3GB of ram, Core 2 Duo processor 1.60ghz. Kernel 2.6.32.21. I had enabled composite and it's working fine. And Install all the suggested packages for structure-synth.

mariocesar@laptop:~$ structure-synth

mariocesar@laptop:~$ structure-synth --debug

I must add that building structure-synth from source, also had a segmentation fault

~$ sudo apt-get install build-essential libx11-dev mesa-common-dev libgl1-mesa-dev libglu1-mesa-dev subversion libxext-dev libqt4-opengl-dev
~$ svn co https://structuresynth.svn.sourceforge.net/svnroot/structuresynth/trunk structuresynth
~$ cd structuresynth
~/structuresynth$ qmake-qt4 -project -after "CONFIG+=opengl" -after "QT+=xml opengl script"
~/structuresynth$ qmake-qt4
~/structuresynth$ make
~/structuresynth$ ./structuresynth
Fallo de segmentación
~/structuresynth$ echo ":-("

I follow this instruction to build from source http://structuresynth.sourceforge.net/download.php

Same Error on my Acer TravelMate 4060

/var/log/syslog
structure-synth[1540]: segfault at 4bc ip b76b6516 sp bf8251cc error 4 in libGL.so.1.2[b76b4000+5000]

Fresh Ubuntu Lucid Lynx Installation

Intel Pentium M Processor - 1.73GHz
1.5GB RAM
Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)

I also tried to recompile last svn release of structure-synth package.. Nothing at all...

[ghendrix (ghendrix-)]

I got the same error on my Lenovo T400 when using the package from ubuntu

Building from source got the same result...

[Chip VanDan (chip-vandan)]

Same problem here:

structure-synth 1.0.0-1
Ubuntu Studio 10.04 Kernel 2.6.33-29-realtime
GNOME 2.30.2

Also tried sudo structure-synth and got a little bit more output, but still ended with segmentation fault

Error: "/var/tmp/kdecache-airlynx" is owned by uid 1000 instead of uid 0.
(8602) KIconCache::Private::themeDirsChanged: Theme directory has been modified
Segmentation fault

Same problem here on lucid. I have backported the natty package to lucid and that one segfaults as well.

[Rolf Leggewie (r0lf)]

not sure if this is of any help, but here is a gdb backtrace for the lucid package

and the same for the natty package (running on a lucid host) with the dbg package installed alongside

Assuming this affects natty itself as well. Setting appropriate milestone so that natty hopefully won't ship with a program that does nothing but segfault. Feel free to remove the natty milestone if you disagree.

[Martin Pitt (pitti)]

If someone wants to work on it, sure. But otherwise this is also fine to fix in an SRU.

[Rolf Leggewie (r0lf)]

retarget to precise release. I think the program should either be fixed by release time for the LTS or the package dropped. We've been shipping a segfaulting package for four releases already.

I wonder why Debian doesn't appear to get reports about the segfault. Maybe this is a difference in one of the underlying libs?

[Rolf Leggewie (r0lf)]

The segfault I get by running upstream r310 compiled from source is a bit different it seems.
