[Bug fortran/32375] New: not vectorized: can't determine dependence (array sections)

[tprince at computer dot org]

gfortran -O2  -ftree-vectorize -ftree-vectorizer-verbose=2 -c -v s414a.f

The source and destination sections of aa(:,:) do not overlap, unless there is
a subscript over-run.  Even that case could be taken care of by loop reversal.

This is a simplification of a case from:
