ICE with slice in a generic struct

[14427]

The following code causes an internal compiler error:

fn foo<T>() {
    let _x: Bar<T> = Bar{ arr: &[] };
}

struct Bar<T> {
    arr: &[T],
}

fn test_foo() {
    foo::<()>();
}

Switching the &[T] to a Option<T> makes it go away.

This test case builds for me on incoming.

Ah, the stage0 compiler does ICE. Maybe we just need to snapshot.

I started a snapshot.

That fixed it.
