The same failure for these, for both x86_64 and i686 with -msse2:

I can't reproduce the failure for gcc.c-torture/execute/simd-2.c compilation as
reported in http://gcc.gnu.org/ml/gcc-testresults/2005-01/msg00595.html. Is
there a problem with:

simd-2.c: In function 'verify':
simd-2.c:26: warning: incompatible implicit declaration of built-in function 'abort'
simd-2.c: In function 'main':
simd-2.c:71: warning: incompatible implicit declaration of built-in function 'exit'

gcc.dg/simd-2.c crashes with:
gcc.dg/simd-2.c:48: internal compiler error: in gen_lowpart_general, at
rtlhooks.c:58
Please submit a full bug report,
with preprocessed source if appropriate.

gcc.c-torture/execute/simd-6.c failure is fixed on current mainline.
