rustc 1.13.0 hangs/out of memory

[ctsa]

I'm using the latest stable release (1.13.0) installed via rustup on Ubuntu 16.04. I ran into a compiler hang after a copy/paste slipup, and reduced the testcase down to the following:

main.rs:

fn main() {
    extern crate rand;
    use rand::Rng;
}

What I see when compiling is:

$ /usr/bin/time -v rustc main.rs 
fatal runtime error: out of memory
