It appears that the failure is not always happening. On Ubuntu 22.10 you might need to try multiple times before a segmentation fault occurs. On macOS I haven't seen a segmentation fault so far.

While rolling back, that is the 1st one that doesn't coredump on self-testing for me.

I don't see any such failure on at least 5 platforms I've tested.
Both of you (@polaris6262 and @drawkula) seem to have different platforms since the compilers are very different. Will you identify what host systems (and versions) you are seeing this problem on?
