ICE: no entry found for key

[nazar-pc]

Summary

I was working on code and caught this ICE, so I though I'd report it in case it is useful, but I made no attempts to minimize it.

Reproduction steps:

• clone https://github.com/subspace/subspace/tree/clippy-ice-panic-reproduction
• cd crates/subspace-farmer
• cargo clippy --all-targets

rustc version: 1.78.0-nightly (c475e2303 2024-02-28)
platform: x86_64-unknown-linux-gnu

query stack during panic:
#0 [hir_owner_parent] getting HIR parent of `commands::farm::farm::{closure#0}::{closure#11}::{closure#1}::{closure#0}::{use#0}`
rust-lang/rust-clippy#1 [check_unused_traits] checking unused trait imports in crate
rust-lang/rust-clippy#2 [analysis] running analysis passes on this crate
end of query stack

[y21]

Moving to the rust-lang/rust issue tracker, since there aren't any clippy frames in the backtrace and the backtrace also suggests it happens while checking for unused traits, so most likely a bug in the compiler

[workingjubilee]

No repro, @nazar-pc. Try using the latest Rust toolchain instead of a pinned nightly.

[matthiaskrgr]

could be #121096

[nazar-pc]

Indeed, I should have checked latest nightly
