Same error message as #6396, #7400 and #7741. (The examples are sufficiently different that I'm unwilling to close as a duplicate without further investigation.)

For reference, this should work with:

fn parse<'a>(header: &'a str) -> &'a str {
    ...
}

probable subbug of #4846

Closed by #10153, relevant tests already appear to be checked in.
