Bug: Clippy Crash

[ens-scmeeu]

NOTE: Apologies that this is likely going to be a very unhelpful bug report. The codebase is a company proprietary one so I can't share much (I can probably share small snippets if helpful). Let me know what else you need and I will see what I'm allowed to share. Thanks for making these great tools.

Clippy crashed when used in conjunction with cargo watch (cargo watch -x clippy). It was working fine, I made a code edit, saved, and then it crashed. The file that triggered the crash per the below report is not the one I was working on when it occurred (it does use the module I was working on). Also, when I did cargo clean and ran clippy again, no crash occurred, so the bug seems to be in relation to incremental scanning possibly. My code actually compiled successfully, so it wasn't due to an error in my code either (Also, FYI before I did cargo clean I did cargo build and cargo check and both worked fine).

Looks like the same issue as #7927.

It seems to be rustc issue, so I'm closing this.
