Tested on commit rust-lang/rust@1062b69. Direct link to PR: <rust-lang/rust#66250> 💔 rustc-guide on linux: test-pass → test-fail (cc @amanjeev @spastorino @mark-i-m, @rust-lang/infra).

Leaving a note here that if we don't beta accept this PR we should make sure to open an issue tracking this regression so we don't forget about it. |

There was a problem hiding this comment.
