Description
I'm reporting because an unexpected panic happened on running cargo clippy.
On the other hand, cargo check succeeds without a warning.
The problem is that, if I created a new git worktree (that is, made a exact copy of src/, rust-toolchain, Cargo.{toml, lock} but not of target), the error does not reproduce. So I'm not sure what is the appropriate next action.
Here are the code that is causing the error. Also I .tar.gz-ed the current worktree.
I'm now leaving the worktree as-is just in case, so I may respond any troubleshooting steps.
