Description
This seems to be related to #42867, though not entirely the same.
I am in the process of cargo publishing my crate (multiple crates in a workspace project) imag v0.5.0 (from this commit).
Instead of a normal compile process, I got this:
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/blob/master/CONTRIBUTING.md#bug-reports
