--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
I wonder if it's the badly tested interaction between IPA opts and IPA PTA,
I assume -O2 -ftree-vectorize instead of -O3 isn't enough to reproduce?

I don't think that GCC 11 working means anything - IPA PTA doesn't get
much changes, so it's likely just now actually doing sth meaningful (bad)
with IPA PTA info.=
