--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Might be a testsuite artifact in not reaching the cost model check but
rejecting vectorization earlier (try bumping N to 32, after peeling for
alignment no
vectorized iteration would be left so we don't peel for alignment anymore
thus we can't handle the store).
