sauerbraten backtrace

Note that shaders have to be enabled in the game to get the assertion failure.

r300 compiler: workaround for sauerbraten crash

The game always run fine before the recently added assert. The attached patch
uses _mesa_problem instead of the assert. Please apply the patch to the 7.8
branch until the real bug is fixed.

I've committed a fix to the 7.8 branch. The game now works here with r300c and
shaders enabled. Closing...
