08:11 <josch> hi, my gajim crashed with a segfault in Debian Trixie with mesa 25.0.7. I captured the following backtrace in gdb: https://paste.debian.net/1394288/ That's the line the bt points to: https://sources.debian.org/src/mesa/25.0.7-2/src/gallium/drivers/panfrost/pan_fb_preload.c#L876

08:11 <josch> what would you like me to investigate in gdb to figure out what happened here?

08:15 <bbrezillon> josch: the best would be to create an issue here https://gitlab.freedesktop.org/mesa/mesa/-/issues/new, ideally with an apitrace trace, so we can easily reproduce

08:26 <josch> bbrezillon: do i just ran gajim with "apitrace trace --api=gl"? Still with gdb for the backtrace?

08:27 <josch> (never used apitrace before)

08:48 <bbrezillon> josch: ok, so I guess the first question is, is this a regression?

08:49 <bbrezillon> if it is, you can capture the trace with a working version

08:50 <josch> If it is a regression, then it is one from the last Debian stable release two years ago which I guess is a bit long in the past? :) Unfortunately, i don't have a quick reproducer. I leave gajim running a while and at some point it quits with the backtrace above.

08:53 <josch> okay, i got a python3.13.trace but it's just 800 bytes small -- does that check out?

08:54 <bbrezillon> you can try to replay the trace, and see if it works

08:54 <bbrezillon> 800 bytes is not much, indeed

08:55 <josch> i never used apitrace before, so i would not know how to replay the trace -- should i just post what i have?

08:55 <josch> (to the issue tracker i mean)

08:56 <bbrezillon> apitrace replay

08:57 <josch> gives me:

08:57 <josch> Rendered 0 frames in 0.00228443 secs, average of 0 fps

08:58 <bbrezillon> can you build mesa from source?

08:59 <bbrezillon> (yep, that's an empty trace)

09:03 <bbrezillon> josch: maybe just open the issue with what you have, and I'll see if I can reproduce

09:58 <josch> yes, building mesa from source is no problem

10:01 <josch> i'll build latest git HEAD and then run gajim with LD_LIBRARY_PATH set to $prefix/lib yes?

10:07 <bbrezillon> yep, sounds good

10:08 <josch> what meson option would i have to pass to enable debug symbols?

10:08 <josch> or does it not matter?

10:09 <bbrezillon> --buildtype=debugoptimized IIRC

10:09 <bbrezillon> but that's the default

10:10 <josch> ah okay :)

10:21 <diederik> josch: https://snapshot.debian.org/package/gajim/ for quite a few intermediate versions? Possibly useful to first see if you can still reproduce it with the version in Experimental (2.3.4-1)

13:02 <josch> yes, also a good idea, i'll rebuild that version for trixie and see what happens

13:05 <josch> it will all take a bit because package versions in trixie are already too old to build gajim 2.3.4 so i have to backport more things...

13:05 <josch> (and my a311d is not the fastest processor :D)

13:05 <bbrezillon> np

13:05 <josch> thank you all for your help, i now have things to investigate before i "bug" you again :)

13:05 <bbrezillon> don't hesitate to open an issue when you're all set

13:05 <josch> thank you! :)

22:12 <josch> hm... no crash yet with mesa from git :)
