(In reply to comment #9)
I've confirmed that the problem is caused by '-ftree-vectorize' passed to
compile gcc. More precisely, a 'movdqa' instruction in constraint_operands()
accessed an unaligned memory.

Is it possible that the reason may be that I compiled gcc with additional
CFLAGS? I added -march=pentium-m -ftree-vectorize -mfpmath=sse,387 and
-fomit-frame-pointer in addition to -O2.
