rustc prints unexpected token in infinite loop

[brson]

Parsing this

extern crate core;

use core::marker::PhantomData;

static mut my_static: u64 = init();

const fn init() -> u64 { 2 }

fn main() {
    let s: SBox<u64> =
}

struct SBox<T>(&'static mut T);

impl<T> SBox<T> {
    unsafe fn from_static(data: &'static mut T) -> SBox<T> {
        SBox(data)
    }
}

Spews this repeatedly:

examples/example1.rs:19:1: 19:2 error: unexpected token: `<eof>`
examples/example1.rs:19 }
                        ^
examples/example1.rs:19:1: 19:2 error: unexpected token: `<eof>`
examples/example1.rs:19 }
                        ^
examples/example1.rs:19:1: 19:2 error: unexpected token: `<eof>`
examples/example1.rs:19 }
                        ^
...
