--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think we're doing sth unsupported - prologue peeling for
LOOP_VINFO_EARLY_BREAKS_VECT_PEELED.  The problem is that we only late
decide whether we do vect_use_loop_mask_for_alignment_p and I'm not sure
whether that variant works.

Testing a simple patch.
