SuperTuxRacer 0.7(which is Irlicht based) Memory Faults on initialization when
using gallium libGL.so, but it works w/o any problems using Mesa Classic libGL.
I gues it happens due to VBO bugs in r300g, which arent avaible in classic
Mesa.
I know it works using r600g because of answers from many persons.
I am using fresh airlied's D-R-T kernel with DDX/DRI/Mesa from Master.
I got multilib system, but STK and 99% apps I am using are 64bit. Gfx card is
FireGL V5200/Radeon X1600 inside T60p.

There are logs, etc:

There is original thread:
http://phoronix.com/forums/showthread.php?33119-SuperTuxRacer-0.7-and-r300g-MemoryFault
And like Qaridarium stated, I got also similar problem with warzone2100 (when
looking at gdb backtrace related to VBO/Vertices)

After some playing with vars I found that game STK doesnt work with
LIBGL_ALWAYS_SOFTWARE=1 (Gallium on softpipe), but works with
LIBGL_ALWAYS_INDIRECT=1 (because of fallback to Mesa Classic).
Not sure about warzone witg softpipe, because it segfaults after starting
campaign, and waiting for menu on siftpipe would take a years.
