function calls in statics cause internal compiler error

[sj6219]

Source is very simple.

//
//
static F : Box< Fn(i32) -> i32 > = Box::new(move |x:i32| x);

fn main() {
}
//
//

this code generate fault as follows.

src\main.rs:2:34: 2:58 error: function calls in statics are limited to struct an
d enum constructors [E0015]
src\main.rs:2 static F : Box<Fn(i32) -> i32> = Box::new(move |x:i32| x);

This causes an ICE on 1.1.0. This does not cause in ICE on 1.2.0 beta.

I assume this caused by the use of a static closure. If so, this is a duplicate of #25180
