--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
19675 /* When lone_idx is not 0, it must from second op(count == 1).
*/
19676 gcc_assert (count == (lone_idx ? 1 : 3));
(gdb) p count
$5 = 3
(gdb) p lone_idx
$6 = 3
and d->perm[] is { 7, 4, 4, 0 }
maybe the function expects some canonicalization that isn't done?
