note: Clippy version: clippy 0.1.51 (04caa63 2021-01-30)

query stack during panic:
#0 [analysis] running analysis passes on this crate
end of query stack

Let me know if I need to provide any other information. This is emitted during the lint of an internal tool that is not publicly available, so I can't provide a reproducible environment.

EDIT: cargo clippy --fix -Z unstable-options --features "$FEATURES_EXPAND" -- -A clippy::correctness was the command to build it. $FEATURES_EXPAND is populated with all features that are required for the build.

It seems to be related with rust-lang/rust#81614.

According to rust-lang/rust#81614 (comment), ICE seems to be resolved, so I'm closing this. If you still have any problems, feel free to reopen this.
