task 'rustc' has overflowed its stack when compiling cyclic structs and enums

[ryantm]

This code produces a stack overflow in rustc when compiled:

pub struct A {
    b: Option<B>
}

pub struct B {
    a: Option<A>
}

pub enum C {
    D(B)
}

fn main () {}

Output:

$ rustc main.rs 
task 'rustc' has overflowed its stack
Illegal instruction (core dumped)

My environment:

$ rustc -v
rustc 0.11-pre-nightly (d35804e 2014-04-18 00:01:22 -0700)
host: x86_64-unknown-linux-gnu
$ uname -a

Closing as a dupe of #4363, but thanks for the report!
