Just create a main.rs with the following contents:

code snippet to reproduce:

fn test_parser_error_bad_length() {
    assert!(matches!(
        drive_parser(&mut parser, data, false),
        Err(TarParserError::CorruptField {
            field: CorruptFieldContext::PaxKvLength,
            error: GeneralParseError::ParseInt(ParseIntError { .. })
        )}) // the first round bracket in this line causes the errors
    ));
}
