I've been testing using the Cell SDK3.0, and I can compile the program. I've
used -O3 and -ftree-vectorize flags. The gcc version provided by the SDK is
4.1.1.

File generated using the flag -fdump-tree-vect

As it seems that error comes from the vectorizer (see the gdb output), I
thought that this information is useful.
