ICE after cargo test --workspace, not reproducible

[Kinrany]

I ran cargo test --workspace after an equivalent of a git-bisect session. Rust-analyzer was running in parallel.

Running cargo test --workspace for the second time did not result in the same error, so I can't really reproduce and provide a minimal code example, sorry.

Error output
