Looks like regression, as with `net-im/teams-1.4.00.7556` all seems fine.
Please disable USE=system-ffmpeg for teams. It is known to fail.
(In reply to Stephan Hartmann from comment #2) > Please disable USE=system-ffmpeg for teams. It is known to fail. Forgot to say, that was already the case: # equery u teams ... U I - - system-ffmpeg : Use the system-wide media-video/ffmpeg instead of bundled. + + system-mesa : Use the system-wide media-libs/mesa instead of bundled. How about 'system-mesa'?
system-mesa is basically swiftshader now. Are you running teams in wayland?
(In reply to Stephan Hartmann from comment #4) > system-mesa is basically swiftshader now. Are you running teams in wayland? Nope, xorg-server-1.20.13-r1. Kernel is 5.13.19-gentoo.
Can you try teams-1.4.00.26453?
With teams-1.4.00.26453 (no system-ffmpeg, irrespective of USE=swiftshader) it looks the same, though segfaults in libpthread now.

Let me know if you need a backtrace.
I'm seeing the same, both 13653 and 26453 crash immediately when joining a meeting with: traps: teams[6507] general protection fault ip:7f82a331c904 sp:7f82b83db2d8 error:0 in slimcore.node[7f82a0d27000+2ff1000] ...and the app restarts. 7556 is the last one working for meetings, but screen sharing is there broken and throws a: teams[15834]: segfault at 7fa9b2ffd910 ip 00007fa9d0b1b13e sp 00007fff305f6080 error 4 in libpthread-2.33.so[7fa9d0b18000+f000] This is a X-based setup, Intel integrated graphics, with -swiftshader -system-ffmpeg -system-mesa, and I also tried disabling GPU acceleration in Teams settings.
I still can't reproduce. Can someone try to get a backtrace?
maybe related to compositing on/off?

Will provide a bt. XFCE4 here with compositing disabled, BTW. @Morton, if you wanna give it a try: https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces

Comment on attachment 747762 [details] GDB backtrace for teams-1.4.00.26453-r1 Trace obtained from core dump. Teams build with splitdebug feature.
I have two AMD64 Linux machines - personal and work. Both run Gentoo, but separate installations. Both are older Intel Core i7 machines using Intel graphics / X11. On my work machine, teams has been solid for the last two years, never crashing. I do a lot of video and audio calls, including screen sharing. I have only just tried to use teams on my personal laptop, but I am getting repeated segfaults in libpthread-2.33.so within a few seconds of joining any call.

Right now I don't have both systems in front of me, the first thing I will do is check that the same version is running on both.
You may want to force system-ffmpeg(need to edit the ebuild for that) System ffmpeg may need a patch: cat /etc/portage/patches/media-video/ffmpeg/av_max_alloc_0.patch --- ./libavutil/mem.c.org 2020-10-07 19:22:30.286728200 +0200 +++ ./libavutil/mem.c 2020-10-07 19:24:04.039885660 +0200 @@ -71,6 +71,8 @@ static size_t max_alloc_size= INT_MAX; void av_max_alloc(size_t max){ + if (!max) + max = INT_MAX; /* be compatible to older < 4.3 versions */ max_alloc_size = max; } At work we use this in various Intel systems without problems for quite a while.

I'm hitting this issue, that whenever starting/joining a (test) call, Teams crashes. I've tried with/without system-ffmpeg, I've downgraded from 1.5 to 1.4, I've removed the cache at "~/.config/Microsoft/Microsoft Teams". None of these things fixed it. This started happening yesterday and I cannot pinpoint the cause. Two days ago, it still worked.

A possible workaround (at least that's what I think fixed my issue) is to complie and run pulse audio. If you are already running pulseaudio, I don't know of anything else that will help.
I (and my company) run with system-mesa/system-ffmpeg with patch: cat /etc/portage/patches/media-video/ffmpeg/av_max_alloc_0.patch --- ./libavutil/mem.c.org 2020-10-07 19:22:30.286728200 +0200 +++ ./libavutil/mem.c 2020-10-07 19:24:04.039885660 +0200 @@ -71,6 +71,8 @@ static size_t max_alloc_size= INT_MAX; void av_max_alloc(size_t max){ + if (!max) + max = INT_MAX; /* be compatible to older < 4.3 versions */ max_alloc_size = max; } for years now. However I don't think the SEGV has much to do with that. slimnode depends on alsa-lib so perhaps USE flags make a differnce, we have USE="python thread-safety" for alsa-lib

Thanks for this suggestion. I am running pulseaudio, but apparently it was crashing and restarting regularly the last two days. Changing from it to autospawn and using the user systemd socket activation fixed its behavior after a reboot. At that point, Teams did not crash anymore.

FYI. I've been using teams-for-linux for a while from overlay "nitratesky": https://gpo.zugaina.org/net-im/teams-for-linux Source code here: https://github.com/IsmaelMartinez/teams-for-linux It works like a charm :-) might be worth considering an official ebuild for it..
