--- Comment #5 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
For GCC 6, this is just a testcase error. The failing assertion requires this
clause now that we can vectorize the loop using misaligned loads/stores:
{ target { ! vect_hw_misalign } }
I'll get that fixed shortly, then see what's up on 4.9 and 5.
