--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I can reproduce what you observe with -O3 -fwhole-program
-fsanitize=unreachable
(without the sanitize it gets into an infinite loop).  -fno-ipa-cp-clone avoids
the issue (whatever it is exactly).

Can you attach un-preprocessed source as well?  You seem to be not using any
non-standard header files.
