tenso.f:811:0: internal compiler error: Segmentation fault: 11
Please submit a full bug report,
with preprocessed source if appropriate.
See <<a href="http://gcc.gnu.org/bugs.html">http://gcc.gnu.org/bugs.html</a>> for instructions.
This ICE is not triggered at -O2 or with any of the flags enabled by -O3 added
to -O2. It requires -O3 explicitly. The attached de_vectorize_bug.tar.bz2
archive contains the files required to reproduce this failure.</pre>
