Sorry, I wasn't very clear there.  I was adding options to the default set.

Compiling as-is using the default options the run will fail.

Adding -fno-tree-loop-vectorize the run will fail.

Adding -fno-tree-slp-vectorize the run will succeed.  Of course just using
-fno-tree-slp-vectorize also allows the run to succeed.

The specific module that breaks things is shell2.fppized.f90.  When I compile
just it with -fno-tree-slp-vectorize also the run succeeds.
