Compiler bug with misspelt enum name

[ns-sundar]

enum Token {
Num(i32),
AddSub(char),
MulDiv(char),
LeftParen(char),
RightParen(char)
}

fn main() {
println!("Hello World\n");

}

[allow(dead_code)]

fn postfix_from_infix(infix: Vec) -> Vec {
let postfix = Vec::::new();

for token in infix {
match token {
Toekn::LeftParen(_) => break,
_ => {}
}
}

postfix
}

I misspelt the enum Token as Toekn. The compiler panics.
C:\UserData\Tech\Rust\expr\src>rustc --version
rustc 1.10.0 (cfcb716cf 2016-07-03)

Fixed on beta/nightly.

Working/minimized reproduction:

enum Token {
    LeftParen(char),
    RightParen(char),
}

#[allow(dead_code)]
fn postfix_from_infix(infix: Vec<Token>) {
    for token in infix {
        match token {
            Toekn::LeftParen(_) => {},
            _ => {}
        }
    }
}

fn main() {}
