--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Ok - so this is basically a "false" hybrid SLP stmt (the group p1[0], p1[1] is
there for no good reason).  We _do_ actually "share" the whole group so you
could argue we should mark the SLP as hybrid.

But well, it's probably easiest to make the assert less strict here (until a
"real" problem shows up with this).

Testcase reproduces on x86_64 with -msse4.
