Flood of unexpected token: `<eof>` errors triggered by foo(|_|)

[0x7CFE]

The easiest way to reproduce the error is to compile the following code:

pub fn test() {
    foo(|_|)
}

After I try rustc report.rs -o test I get the following output:

report.rs:3:1: 3:2 error: unexpected token: `<eof>`
report.rs:3 }
            ^
report.rs:3:1: 3:2 error: unexpected token: `<eof>`
report.rs:3 }
            ^
report.rs:3:1: 3:2 error: unexpected token: `<eof>`
report.rs:3 }
            ^
(ad infinitum...)

I expect to get the single line error output, not the flood.

Looks like it is a fairly recent bug. It reproduces on the nightly build, yet version (rustc 1.7.0-beta.4 (5ed7d4e31 2016-02-26)) works ok.

I checked on my machine and through versions available at http://rust.godbolt.org/

#32479 might help.

@nagisa It's actually fixed on master.
