The same issue with GCC 4.3.3 (i686-pc-linux-gnu).

C source:
http://svn.savannah.gnu.org/viewvc/*checkout*/trunk/kqemu.c?root=qemu&revision=6338&content-type=text%2Fplain

cc1 -O3 -march=pentium4 kqemu.c

Offending asm code:

kqemu_cpu_exec:
...
        movl    8(%ebp), %ebx
...
.L96:
        movdqa  (%ebx), %xmm0  // segmentation fault
