--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed the symptom.  We do quite some loop opts, but adding
-fno-unswitch-loops -fno-tree-vectorize does not resolve the issue.  Using -O2
instead of
-O3 and -fno-tree-vectorize still reproduces it on trunk, but GCC 14.2 is
OK.

Definitely needs reduction.
