seen with 4.4 branch 20090822 (biarch compiler defaulting to 31bit), not with
4.3 and trunk 20090821, the ICE can be avoided using -O2 instead of -O3.

$ gcc-4.4 -O3 -c Any3Byte.i
../../../src/share/native/sun/awt/../java2d/loops/Any3Byte.c: In function
‘Any3ByteSetSpans’:
../../../src/share/native/sun/awt/../java2d/loops/Any3Byte.c:73: internal
compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.4/README.Bugs> for instructions.

No useful information in the backtrace.

Can't reproduce with x86_64-linux -> s390x-linux cross (-O3 -m31).

sorry, the last comment should have gone to PR33263, I'll need to find the time
to recheck this issue.
