--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed on the GCC 11 branch head, I suspect it's something to do with SLP
patterns and I cannot reproduce with recent GCC 12.
Tamar, are there any fixes that need backporting in this area?
Martin, can you bisect what fixed it on trunk?
