--- Comment #20 from Thomas Rohloff v10lator@myway.de --- I'm going crazy. I just removed the bad patch from 3.8-rc1 and updated mesa to newest git version (therefore I had to stay at a9048aa6e6abcbeb498ef286630be30729aebaf3 cause of a patch missing in the bisected tree) and the bug is back again.
I don't know how to find the root of it and I have headache cause of it. There seems to be something really wrong with memory management but it's way over my head.
