A snippet from /var/log/messages
Starting sometime after 17.2.5, all 17.3.0_rc versions I've tried have caus=
ed
some applications to crash randomly. On occasion an application will take
longer to crash, but it almost always does.
My graphics card reports as Advanced Micro Devices, Inc. [AMD/ATI] Lexa PRO
[Radeon RX 550] (rev c7)
My distro is Gentoo ~AMD64, and my mesa flags are "classic d3d9 dri3 e=
gl
gallium gbm gles2 llvm nptl opencl osmesa wayland"
I almost never see anything in dmesg or /var/log/messages, with the excepti=
on
of a few messages that are attached.
I should add that it seems to only be the application that crashes, I have =
not
noticed any ill effects on any other part of my system. In addition, it does
not seem to be application or even language dependant, having noticed it in=
a
Unity game (which is C#) and a Java game.
To reproduce it, I simply start the application and begin using it, after s=
ome
time it will simply crash.

Thanks for the report. Maybe try a clean rebuild? Failing that, please provide a backtrace with debug symbols, otherwise ther= e's no hope of fixing this if it is a real bug.
Alright, I rebuilt mesa with debug symbols, and I got the foll=
owing from gdb
(along with a bunch of useless stuff regarding threads)
