ICE when build serde during work on my PR

[Mingun]

Code

The bug appeared when I worked for my PR for serde, there is a commit that introduces it: Mingun/serde@5ef91dd
My serde/Cargo.lock attached.

To reproduce:

1. Checkout https://github.com/Mingun/serde/tree/rustc-bug
2. Maybe exact versions of some crates required, so place Cargo.lock.txt into root of working copy and remove the .txt extension (GitHub restriction)
3. cd ./test_suite
4. Run cargo +nightly-gnu test --features unstable

[Mingun]

The bug disappeared when I ran cargo clean in D:\Projects\serde\test_suite, so it is probably related to intermediate artifacts. I've also tried to switch to another branch before cleanup and got the same ICE.

You're not the first person having this issue. Closing this as a duplicate of #109879.
