rustc (nightly) hangs when put extern crate + use inside a function #36881
Description
When use both extern crate and use on same crate inside a function, the nightly rust compiler hangs forever.
I tried this code (A fresh cargo new):
pub fn foo() {
extern crate rand; // `rand` is configured in Cargo.toml, or any other crate.
use rand::Rng; // or anything starts with ``rand::``
// code here
}I expected it works.
Instead, the compiler hangs and doesn't out put anything.
