[Bug 105599] Re: After many hours of intense use FF finally crashed on Control-T.

[Finn Hakansson]

Hello Hilario,

I ran your commands:

finn at UB01060:~$ TMPDIR=$(mktemp -d)
finn at UB01060:~$ apport-unpack /var/crash/_usr_lib_firefox_firefox-bin.1000.crash $TMPDIR
finn at UB01060:~$ gdb -nx /usr/lib/firefox/firefox-bin -core $TMPDIR/CoreDump -ex 'backtrace full' -ex 'thread apply all backtrace full' -ex 'quit' 2>&1 | tee gdb.log

"/tmp/tmp.SrqkY19500/CoreDump" is not a core dump: File format not recognized
No stack.


Somehow it seems that not even a core dump could be generated. Weird. If
this ever happens to me again I hope I'll get a proper core file.

Sorry for wasting your time. However, I must say that I'm very impressed
with your responsiveness in this matter.

Best regards,
Finn

Hmm, seems that the coredump file got corrupted at some point,

...
++ gdb -nx /usr/lib/firefox/firefox-bin -core CoreDump
++ tee gdb.log
GNU gdb 6.4.90-debian
[...]

"CoreDump" is not a core dump: File format not recognized
(gdb)
...

Can you please verify that the coredump file from the report is still OK
in your system, just follow these instructions:

apt-get install firefox-dbg (you might have to apply sudo here)

Copy and paste in a xterm the following sequence of commands:

TMPDIR=$(mktemp -d) 
apport-unpack /var/crash/_usr_lib_firefox_firefox-bin.1000.crash $TMPDIR
gdb -nx /usr/lib/firefox/firefox-bin -core $TMPDIR/CoreDump -ex 'backtrace full' -ex 'thread apply all backtrace full' -ex 'quit' 2>&1 | tee gdb.log
rm -fr $TMPDIR

That command will run gdb against the coredump file included in the
crash report that was generated when firefox crashed.

Upload the resulting gdb.log to this thread

Thank you in advance.
