--- Comment #25 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
I've verified the patch indeed fixes the test from c#11.  Regstrap in progress.

One nit:  The parentheses in the proposed patch are slightly wrong, should be:

              && (LOOP_VINFO_VECT_FACTOR (loop_vinfo)
                  * GROUP_SIZE (vinfo_for_stmt (GROUP_FIRST_ELEMENT
(stmt_info)))
                  % TYPE_VECTOR_SUBPARTS (vectype) != 0))
