There was a problem hiding this comment.
Do I understand it correctly that this lint output actually originates from write!(&mut v, "\\\n"); in line 44?

Yes. That warning is correct because the format string ends in backslash and newline. The stderr file has double forward slashes because compile test normalizes output by first by replacing double backslash with backslash and then backslash with forward slash. https://github.com/laumann/compiletest-rs/blob/25b681f06935ff697c5736fa85dd32af695b5e69/src/runtest.rs#L2456 |

Looks like a small .stderr update is needed after #3529 https://travis-ci.org/rust-lang/rust-clippy/jobs/466857163#L1076 |
