when building xorg-server with -O3 -fprefetch-loop-arrays and gcc-4.3.1 on an
amd64 linux system, we hit an ICE like so:
texenvprogram.c: In function 'emit_combine':
texenvprogram.c:739: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
older versions of gcc seem to work. building for x86 seems to work.
