This [bors CI failure](https://github.com/rust-lang/rust/pull/110177#issuecomment-1508313026) was almost certainly spurious: ``` thread 'registry::not_found_permutations' panicked at 'assertion failed: `(left == right)` left: `["/index/a-/b-/a-b-c", "/index/a-/b_/a-b_c", "/index/a_/b-/a_b-c", "/index/a_/b_/a_b_c"]`, right: `["/index/a-/b-/a-b-c", "/index/a_/b-/a_b-c", "/index/a-/b_/a-b_c", "/index/a_/b_/a_b_c"]`', src/tools/cargo/tests/testsuite/registry.rs:3187:5 failures: registry::not_found_permutations ``` I think this is the cargo test suite? Hard to say from the logs.
