ICE when incremental compilation

[tengyifei]

Code

the project is too big unfortunately. this happens when compiling 10s of files.

but the compiler told me to attach a file:
rust-ice.txt

I'm seeing this as well. It happens while I am editing my Rust project. If anyone wants to try to repo my project is on GitHub. I had 94 ice files created while creating this changeset (rchriste/OnPurpose@d5e0d36). I editted in VS Code using the Rust-analyzer plug-in.

PS C:\Users\russ-\repo\OnPurpose> rustc --version --verbose

Here is one of the ICE files created rustc-ice-2024-04-28T13_27_42-30880.txt

And another
rustc-ice-2024-04-28T13_29_42-28356.txt

This did not start happening to me until after I tried switching to the nightly Rust.
