ICE with cargo clippy: thread '<unnamed>' panicked at 'forcing query with already existing 'DepNode'

[paolobarbolini]

Summary

This is happening on a closed source codebase. I might subsequently try minimizing if it helps.
cargo check and cargo build work correctly.

EDIT: code posted at: https://github.com/paolobarbolini/rust-clippy-issue-9819-repro

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust-clippy/issues/new

note: Clippy version: clippy 0.1.66 (73c9eaf 2022-11-07)

query stack during panic:
#0 [try_destructure_mir_constant] destructuring MIR constant
#1 [analysis] running analysis passes on this crate
end of query stack

Thanks for the report!

This seems to be similar to #9845. And there are reports that the latest nighlty has fixed this, so could you try it? #9845 (comment)

[paolobarbolini]

I updated to the latest nightly and did a clean build, but it's still happening. I'll try to see if I can reduce it and post the code

[paolobarbolini]

I was able to reduce it and I posted it in this repo:
https://github.com/paolobarbolini/rust-clippy-issue-9819-repro

[giraffate]

#10131 looks like the same issue.

[dswij]

#10131 looks like the same issue.

And #10298

No longer reproduces on 1.84.1.
