[apport] gaim crashed with SIGSEGV in realloc()

[Michael B. Trausch]

Binary package hint: gaim

There seem to be a lot of problems with this software. I know that I have submitted a problem in the past myself, but this one seems different. It crashes far more frequently than on my laptop (the difference being that the laptop is a uniprocessor 32-bit system, and this is a dual-core AMD64 system). Usually, it seems to crash right after I receive notification that someone has signed on, which comes through gaim-festival and gaim-libnotify.

OTOH, it does not happen *every* time this happens, but when it does happen, it seems to happen within 10 seconds of the notification being issued, reasonably predictably. I cannot go through all of the GAIM bugs to figure out which is what, but I have the feeling that whoever is flagging those issues will know if this is truly a dup or not. If it is, sorry for the dup bug.

See the attached stacktrack, which is a little bit better.

Thanks for your bug report. Can you run the app under valgrind and attach the log to the bug report please? http://wiki.ubuntu.com/Valgrind has more information on how to do that.

[Michael B. Trausch (mtrausch)]

Alright. I am running it now, and we'll see how useful that is. The application under Valgrind is next to unresponsive, and so I don't know if it is going to even catch the event that is triggering the crash... It's using up 100% of one of my cores, consistently. :) I will bring data when I have it, though.

[Michael B. Trausch (mtrausch)]

That's funny. As soon as I submitted that, GAIM crashed, stating it was "Killed":

mbt@sage:~/gaim-problem$ G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind -v --tool=memcheck --leak-check=full --num-callers=40 --log-file=valgrind.log gaim
libnm_glib_nm_state_cb: dbus returned an error.
  (org.freedesktop.DBus.Error.ServiceUnknown) The name org.freedesktop.NetworkManager was not provided by any .service files
Killed

Attached is the resulting logfile, compressed.
