Hum I'm new in the rust community, not sure how to report a bug but I listened the compiler telling me to report it and I wanted to help the community in case I found something helpful...

Anyway

[chenyukang]

I think this is another case with #104513

[compiler-errors]

@chenyukang that ICE is not related to this one.

This ICE is fixed on nightly, I think maybe fixed with #101629 but I haven't done the bisection.

[chenyukang]

Yes, the backtrace is different with last one, so the root cause is not same.

[albertlarsan68]

This ICE seems to be fixed on rustc 1.66.0-beta.1 (e080cc5a6 2022-11-01), host x86_64-pc-windows-msvc.
