Description
This program
fn main() {
extern crate libc;
use libc::*;
}seems to cause the compiler too loop endlessly in AST validation, allocating more and more memory:
$ rustc -Z time-passes oom.rs
warning: the option `Z` is unstable and should only be used on the nightly compiler, but it is currently accepted for backwards compatibility; this will soon change, see issue #31847 for more details
