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 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.

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

I'm gonna close this since it's fixed on beta, and probably will not be backported to stable.
