I think this is an LLVM bug (rust nightly recently upgraded to LLVM 18): llvm/llvm-project#82261

[eigmax]

Any possible fix/updates for this?

[Amanieu]

This is fixed in LLVM main and is currently being backported to the 18.x branch in llvm/llvm-project#83336. Once that is merged this will need to be cherry-picked into rustc's fork of LLVM. See rust-lang/llvm-project#168.

[ForsakenHarmony]

Just needs to be merged into rust now: rust-lang/rust#122559

[ForsakenHarmony]

Fixed in the latest rust nightly
