(In reply to Nicolai Hähnle from comment #3)
I haven't been able to reproduce this with Mesa master and LLVM r283219 so far. Does this happen with clean re-builds?
Yes, all LLVM and Mesa builds were done through the package manager, starting with an empty build directory. And I don't use ccache.
I just re-checked with an updated LLVM & Mesa and the game still crashes: Mesa: git-0e85ff3 LLVM: r283225
I also verified that it still starts properly with amdgpu-pro (running on top of the upstream 4.7.5 amdgpu module).
If this still happens with current LLVM and clean re-builds, please provide logs with R600_DEBUG=vs,tcs,tes,gs,ps,cs.
The wide range of different backtraces suggests that it might be random memory corruption, so running under Valgrind may also be worth a shot.
It does look like it. I'll get a valgrind memcheck log, but will first need to recompile a couple of libraries because valgrind still doesn't support all the instructions of my CPU :/
