Wrong cargo fix output

[SDesya74]

I tried this code:

fn main() {
    let vec = Vec::<(usize,)>::new();
    let mut v: usize = 0;

    for (mut i,) in vec.iter() {
        foo(&mut v, i)
    }
}

fn foo<T>(_: &mut T, _: T) {}

Git repo for reproduction: https://github.com/SDesya74/rustfmt-err

I expected to see this happen: cargo removes mut and adds dereference to i.

Instead, this happened: cargo fix shows error:

Output

    Checking rustfmt-err v0.1.0 (/Users/me/dev/tests/rustfmt-err)
warning: failed to automatically apply fixes suggested by rustc to crate `rustfmt_err`

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
