ICE after renaming trait on nightly 1.80 about rust HOT 5 OPEN

Hey, thanks for your report! This seems to be an incremental compilation bug.
Unfortunately I'm unable to reproduce this as is. Below are my exact steps.
If you are able to consistently reproduce this ICE when renaming the trait,
please tell us the reproduction steps in as much detail as possible. Thanks! :)

git clone https://github.com/tower120/hi_sparse_array.git
cd hi_sparse_array
git checkout 5910c9352d3494084514f68d6a0f684324dea83a
rustup install nightly-2024-05-07 --profile minimal
cargo +nightly-2024-05-07 build
sed -i 's/\bMaybeEmpty\b/Empty/g' **/*.rs
cargo +nightly-2024-05-07 build

from rust.

I also tried

• \b(?<!\[)MaybeEmpty\b → Empty with VS Code search & replace, i.e., every occurrence except intra-doc links like [MaybeEmpty]
• rust-analyzer's rename
• sed -i 's/\bMaybeEmpty\b/Empty/g' src/lib.rs (crate root only)

to no avail

I used RustRover for rename. And compiled with CTRL+F9. Also cargo test --tests.

I get such ICE's from time to time, but not consistently. I also CONSTANTLY loose debug capabilities in random files of project. Both VSCode and RustRover says something like "debuggable file does not have debug info" or that it mismatch.

There is bench.bat in project, It compiles and run project with target-cpu=native. Maybe that is the reason? Maybe build system somehow mess with different build configs?

I also have several chains - nightly, stable, and some 1.7x. Project requires nightly mode (but not nightly chain), and I think I changed default chain previously...

Maybe you could walk several revision back from master, and then incrementally one-by-one go forth and try to compile, bench and test at each revision. That rename is in master branch now.

I couldn't reproduce it either, but I think #126409 might help to deal with that.
