Is this still happening with current Mesa?

Can you bisect xf86-video-amdgpu then? :)

--- Comment #4 from Fabian Maurer  ---
I managed to downgrade mesa to 11.2.2, but the issue persisted. Figured out it
can be fixed by downgrading "xf86-video-amdgpu" from git to stable.
Now I'm not sure wheter this bug is a mesa issue or from that project.

Since I didn't mention it yet, the issue is with (any) wine and
N-Ball(http://www.ragdollsoft.com/nball/). It has a demo and crashes right on
startup.

I'd provide an apitrace, but if it's made with "LIBGL_ALWAYS_SOFTWARE" or
"LIBGL_DRI3_DISABLE", then it replays fine. If made it without, the trace is
cut of before the crashing part.

Also, the bug is non-deterministic. It works most of the time if I edit wine
and put a 1 second sleep before "glXSwapBuffers", maybe a racecondition.

Is this still the right place for this issue?

--- Comment #3 from Michel Dänzer  ---
Assuming you can reproduce the problem with Mesa Git + LLVM 3.9/3.8, you can
stick to the latter for bisecting. If you run into any clang related issues,
you can build Mesa with --disable-opencl for the bisection.

--- Comment #2 from Fabian Maurer  ---
I'd like to, but the older versions fail due to the wrong version of
llvm/clang.
Is there somewhere a tutorial how to compile both together?
