Example:
use std::collections::HashSet;
fn main() {
let mut v = Vec::new();
foo(&mut v);
}
fn foo(h: &mut HashSet<u32>) {
}
Output from playpen:
<anon>:5:9: 5:15 error: mismatched types:

Happens for me on rustc 1.1.0-nightly (f9e53c7f2 2015-04-24) (built 2015-04-25), and playpen is using beta, so it happens on that as well.
