PR110491 still reproduces after my fix (and PHI-OPT fixed the same way). The two other non-deterministic ones don't reproduce before/after (or I misunderstand how they work). > PR 110376 doesn't reproduce for me anymore. I'm going to add this as testcase. So I think there's more analysis necessary and I didn't fix the underlying issues in the other PRs.
