I applied cargo clippy --fix --allow-dirty to

fn main() {

    println!(
        "\nI doing {2} from {1} years and i {0} it",
        "like", 20, "programming"
    );

}

I expected to see this happen: explanation

Instead, this happened: explanation

warning: failed to automatically apply fixes suggested by rustc to crate `ca_p1`

after fixes were automatically applied the compiler reported errors within these files:

  * src/main.rs

This likely indicates a bug in either rustc or cargo itself,
and we would appreciate a bug report! You're likely to see 
a number of compiler warnings after this message which cargo
attempted to fix but failed. If you could open an issue at
https://github.com/rust-lang/rust/issues
quoting the full output of this command we'd be very appreciative!
Note that you may be able to make some more progress in the near-term
fixing code with the `--broken-code` flag

The following errors were reported:
error: invalid reference to positional argument 1 (there is 1 argument)

This is a clippy bug, not a rustc bug. Can you transfer the issue to the https://github.com/rust-lang/rust-clippy repository?
