on bug 65968
from Andreas Ringlstetter
RADEON_DEBUG=noopt is not possible, the pixel shader programs are to big to be loaded without size optimizations. Hard limit of 512 instruction slots per pixel shader: http://developer.amd.com/wordpress/media/2012/10/Radeon_X1x00_Programming_Guide.pdf page 13 This limit is exceeded by far due to all the virtual texturing code, the optimized shader barely fits. I did try it in 9.0 and 9.1 with noopt and I did get past the segfault in peephole_mul_omod() this way, but it did fail then because the resulting shader program was to big. Deactivating hyper-z has no measurable impact, and it didn't prevent the corruption either. Antialiasing hasn't even been enabled in the application by default, so turning it off makes no difference at all.
