I'm seeing a crash on x86 windows due to one of the commits in https://github.com/llvm/llvm-project/compare/08c69b2ef6eeba19956ad24fb7e9d29e9778cbaa...af64f0a6c2e26b3fd1979c1fa380136e5528c9b3, I suspect it's this one. Let me know if you need a reproducer or any other info and I'll see what I can do.
