The code failing seems to be here in os.rs:

#[cfg(unix)]
pub fn pipe() -> Pipe {
    unsafe {
        let mut fds = Pipe {input: 0 as c_int,
                            out: 0 as c_int };
        assert_eq!(libc::pipe(&mut fds.input), (0 as c_int));
        return Pipe {input: fds.input, out: fds.out};
    }
}

It looks like pipe is failing.
