Thanks, Andrew.  I'm also having trouble reproducing it on PPC (under OS X
10.3.4), though.  Same GCC source tree and test source, and:

 % ./g++ -O2 -maltivec -ftree-vectorize -fdump-tree-vect-stats
-ftree-vectorizer-verbose=9 -S 18546.cpp
18546.cpp:9: note: LOOP VECTORIZED.
18546.cpp:6: note: vectorized 1 loops in function.

The generated .t55.vect is a tiny diff away from the x86 version; I'll attach it
and the generated asm.
