ICE when incrementally compiling code

[scrabsha]

Note: cleaning the target directory and compiling again makes the ice vanish. As such, I suspect this ICE to be caused by incremental compilation. If it can help, I have an exact copy of the target which triggers the ICE. I have checked, and I can trigger it again on my laptop. I don't know how portable it is, though.

Code

Too long to be written here. See scrabsha/langgg/ICE-1 instead.

FWIW it looks like it's happening cargo check but not cargo build.

[Aaron1011]

This should be fixed in the latest nightly by #92533

[scrabsha]

Can confirm that Jan 27 nightly fixes the issue. Thanks!
