--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
This is caused by the scalar cond reduction work which now releases SSA names,
leaving invalid IL.
2087 /* Delete original reduction stmt. */
2088 stmt_it = gsi_for_stmt (reduc);
2089 gsi_remove (&stmt_it, true);
2090 release_defs (reduc);
there are two PHIs with uses of _4, but the 2nd is not removed. They
are fully redundant.
