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).

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 :/
