--- Comment #24 from Richard Biener <rguenth at gcc dot gnu.org> ---
So testing with r16-7431-ge55de74d50d236 435.gromacs does not miscompare for me
with -Ofast -march=znver4 on a Zen4 machine. The oldest trunk I have lying
around (r16-5041) also does not reproduce the miscompare, so I'm not sure it's
gone again or I can just not reproduce for one or another reason.

shows it's back, but IIRC you bumped tolerance? Can you see to turn that back
to the default?
