}

error: internal compiler error: non-static region found when hashing a type
note: the compiler hit an unexpected failure path. this is a bug.
note: we would appreciate a bug report: http://doc.rust-lang.org/complement-bugreport.html
note: run with `RUST_BACKTRACE=1` for a backtrace

[tomaka]

Other code that triggers it:

use std::any::Any;

fn foo<T: Any>(value: &T) -> Box<Any> {
    box value as Box<Any>
}

fn main() {
    foo(&5i);
}

@eddyb told me that a similar ICE had been fixed but maybe not yet in the nightlies, I'll check tomorrow if I don't forget
EDIT: still not fixed

[sanxiyn]

@tomjakubowski's code compiles now and @tomaka's code causes a compile error. Neither causes an ICE any more.
