#[deny(warnings) isn't working on E0170

[GuillaumeGomez]

This code compiles without errors:

#![allow(unused_variables)]

#![allow(dead_code)]
#![deny(warnings)]

enum Foo {
    Bar,
    Baz,
}

fn fn1(e: Foo) {
    match e {
        Bar => {},
        Baz => {},
    }
}

fn main() {}

With the following output:

However, the #[deny(warnings)] should make it fail.
