log file

GRID Autosport crashes on start of race.
It seems the same issue of this bug 93352, which is marked as FIXED, but it
isnt, I guess.

I've run steam with this command: LIBGL_DEBUG=verbose steam > log.txt
until the game crashed.

I've attached the log file.

LLVM/mesa/xorg/drm are build from git, 08/06/2016.

Let me know if I can provide more usefull log file.
