firefox crashed with SIGSEGV in __kernel_vsyscall() when I was printing

[berg]

Binary package hint: firefox-3.0

I Browser this page
http://riplinton.blogspot.com/2008/04/using-gnulinux-tools-to-recover-dvd.html

Then I Click to Print (file-> print)
Choose "Print to file"
choose PDF for output format
and click ok
A separate windows popup displaying the progress.
at some 30% stopped and after I played with "alt-tab" , firefox crashed.

seems equal many bug reports reporting crashing ( almost linking with flash : almost site used flash :) , but all need infos because apport cant get them and almost was marked as invalid :(

there is many reports about crashes and hardy is a LTS version. and there is more importance to find the roots.

[berg (berg-foss)]

I use the commands copied from some page from ubuntu and adapt and generate this attached gdb.log

mkdir t
apport-unpack /var/crash/_usr_lib_firefox-3.0b5_firefox.1000.crash ./t
cd t
 gdb -nx /usr/lib/firefox-3.0b5/firefox -core CoreDump -ex 'backtrace full' -ex 'thread apply all backtrace full' -ex 'quit' 2>&1 | tee gdb.log

[berg (berg-foss)]

running this command: strace -r -o trace_firefox1.txt firefox-3.0

I attached the output (big output)

Created attachment 315698
I created a backtrace form cashdump

[berg (berg-foss)]

strace -r when I tested a simple local page and works fine.
after I tested with a page from web and crashed

[Timeless-bemail (timeless-bemail)]

you're kidding, right?

the first bug you linked to is an invalid mess. and you managed to link to the same report twice. hint: don't link to more than one external report, and if the report is invalid, it's probably not something you want qa to read, so don't bother linking at all.

#3 <signal handler called>
^ this is when you crashed. the stuff past this point is just cleanup so that you can run firefox again.

fwiw, your attachment is almost useful, except it's missing the critical bits:
No symbol table info available.
#4 0xb6dde63b in ?? () from /usr/lib/libcairo.so.2
No symbol table info available.
#5 0xb7c1d50a in ?? () from /usr/lib/libnspr4.so.0d

please install the -dbg packages for these libraries. then get a new stack trace.

fwiw, we don't generally have a use for an strace. we need a complete and valid stack trace. these come from things like debuggers such as gdb. however, in order for them to be able to give you a good stack trace, they need debugging symbols. information on installing those symbols (from -dbg packages on your platform) can be obtained from your distro vendor.

as it happens, your vendor even has a wiki page specifically for this product, and it's in one of the bugs you linked to. in general it's a good idea to read things you want others to read....

https://wiki.ubuntu.com/MozillaTeam/Bugs

note that had you read that wiki you'd at least have symbols for nspr. sadly for unknown reasons they don't tell you to install symbols for cairo. please feel free to kindly suggest to them that they add it to the list. (you should really have symbols for: x, glib, gdk, and cairo in addition to the ones they list.)

[berg (berg-foss)]

First. I am not wasting time and efforts for kiding.

I am trying link diverse reports of bugs ( efforts of many many people trying help , inside of your limit of knowledge but are attempting. he may give a hand & no a punch ).
this is a recommendation wherefore bugs alike ( or but also repeated ) they may have faster solution. more bugs reports more people to help (I suppose)

second : in relation to the fact of the first bug is invalid (I showed others), look the review 19, the bug is invalid exactly because do not have a backtrace useful!!!! ( https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/184957/comments/19 )
 Look others commentaries and others bugs report , the number is frightful :(

https://bugs.launchpad.net/ubuntu/+source/firefox-3.0?field.searchtext=&orderby=-datecreated&search=Search&field.status%3Alist=NEW&field.status%3Alist=INCOMPLETE_WITH_RESPONSE&field.status%3Alist=CONFIRMED&field.status%3Alist=TRIAGED&field.status%3Alist=INPROGRESS&field.status%3Alist=FIXCOMMITTED&field.assignee=&field.bug_reporter=&field.omit_dupes=on&field.has_patch=&field.has_no_package=

My bug reports ( and not yet is invalid :)

https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/217032

and I used the instrunctions from https://wiki.ubuntu.com/MozillaTeam/Bugs

I will try install all dbg and dbgsym packages ( https://wiki.ubuntu.com/DebuggingProgramCrash )
using this script
#!/bin/bash
echo on
dpkg -l | cut -c5-40 > /tmp/loop.txt

for arquivo in $(cat /tmp/loop.txt); do
        echo trying DBG "$arquivo-dbg"
        apt-get install -y --force-yes "$arquivo-dbg"
        echo trying DBGSYM "$arquivo-dbgsym"
        apt-get install -y --force-yes "$arquivo-dbgsym"

done

the libcairo2-dbg package is reallly missing from recommendation at mozillateam.

root@unstable-desktop:/home/unstable# dpkg -S libnspr4.so.0d
libnspr4-0d-dbgsym: /usr/lib/debug/usr/lib/libnspr4.so.0d
libnspr4-0d: /usr/lib/libnspr4.so.0d

thank you for his considerations, links and by attention.

I tested with the version at http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9pre) Gecko/2008041504 Minefield/3.0pre

And crashed too

I observed that at java.sun.com main page print to file ( pdf option) always crash
Important: ps option don't crash ( yet :)

the firefox had detect by itself and send the following crash report:

Comments: I was make a test with the lastest nightly trunk to test the bug report https://bugzilla.mozilla.org/show_bug.cgi?id=429071 and continues to crash when I print to file ( pdf option) on site like java.sun.com

This report also contains technical information about the state of the application when it crashed.

[Timeless-bemail (timeless-bemail)]

Unless we have symbols for your cairo, the report won't actually be any more useful than what you've already pasted.

sadly, the output you pasted from crash reporter is absolutely useless. please load about:crashes and copy the bp- id.

we want to get the crash reporter ui improved, but we ran afoul of a localization freeze, so there's probably not much we can do about it for 3.0 :(.

thanks .

I have a report from nightly trunk that crash too.

[Timeless-bemail (timeless-bemail)]

oh, heh, i was wrong about cairo. sorry. in our builds, we build our own cairo. in distro builds, you get system cairo.

thanks, both stacks are useful. although sadly they aren't identical.

I just filed bug 429678, which might be related to this bug?

[Mats Palmgren (matspal)]

I'm pretty sure it's the same problem as bug 429678. Applying the patch
there fixes it for me (on Linux).

Today I tested with the version below and Woks Fine !! Thanks :)

we don't have to fix it in ubuntu as it will automatically land here
once we update to latest upstream.
