--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hmm, and interestingly this fix causes PR66375 to regress again:

FAIL: gcc.dg/torture/pr66375.c   -O2  execution test
...

OK, so that's because my suggested fix is exactly an (incomplete) reversal
of the fix for PR66375 (r6-1346-gb9b79ba4264cf6) :/
