Can you please try again with a more recent version? The upstream
repository is now on v1.24.0
https://gitlab.lisn.upsaclay.fr/texlive/luatex/-/tags
If it's more convenient for you, this same version is included in TeX
Live 2026

FWIW, I'm able to process every font on my system using luaotfload
without any crashes. It takes like an hour and uses >16GB of memory, but
it doesn't segfault. I have no doubt that you found a valid crash; I'm
just adding this to point out that this might be tricky to reproduce.
Thanks,
