--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I'm guessing you hit

                            /* For loop vectorization we now should have
                               an alternate type or LOOP_VINFO_PEELING_FOR_GAPS
                               set.  */
                            if (loop_vinfo)
                              gcc_assert (new_vtype
                                          || LOOP_VINFO_PEELING_FOR_GAPS
                                               (loop_vinfo));

it's always helpful to quote the line an assert happens on given it "moves" a
lot during development.  I can reproduce it with a cross.
