--- Comment #2 from Alex Coplan <acoplan at gcc dot gnu.org> ---
Mine, this should be straightforward: the checking loop is now being vectorised
after the PFA changes which was causing 2 loops to have "Alignment of access
forced using versioning" as opposed to just 1 (as the test expected).  So we
just need to block vectorisation of the second loop with a #pragma.
