[Bug tree-optimization/34038] 176.gcc segfaults when compiled with -O2 -ftree-vectorize -maltivec

------- Comment #3 from janis at gcc dot gnu dot org  2007-12-03 21:57 -------
The failure occurs with "-m32 -O3 -maltivec -fno-strict-aliasing", but not
without -fno-strict-aliasing.  That option is sometimes necessary because of
invalid code in 176.gcc, as described in 
http://gcc.gnu.org/ml/gcc/2002-01/msg00711.html.  Without it 176.gcc. fails
with -m64.

I get the failure with cpu2000 v1.2 plus 176.gcc.64bitgcc40.src.alt and with
cpu2000 v1.3.
