dmesg

Civilization 5, with all DLC, causes a GPU crash on recent git (490621f) on
Radeon R9 270. The game works perfectly on mesa 10.4.2 from Debian unstable,
though. Hardware and kernel are x86-64, but the game (and obviously mesa) is
32-bit.

The crash happens when the game is loaded, probably where the map would first
get drawn.

Mesa was built in a 32-bit chroot and configured with

   ./configure --prefix=/home/sliedes/local/mesa32 --build=i686-pc-linux-gnu
--host=i686-pc-linux-gnu --with-gallium-drivers=radeonsi
--with-egl-platforms=drm,x11 --enable-driglx-direct --enable-gles1
--enable-gles2 --enable-glx-tls --enable-texture-float

LLVM version is 3.6.0, built in release mode.
