Cannot construct a static with a cross-crate tuple struct

[huonw]

// othercrate.rs
pub struct Foo(u8);

static OK: Foo = Foo(1);

// crosscratetuple.rs
extern crate othercrate;

static ERR: othercrate::Foo = othercrate::Foo(1);

fn main() {}

rustc othercrate.rs --crate-type lib compiles fine (other than the dead code warning for OK), but rustc -L . crosscratetuple.rs is not:

crosscratetuple.rs:3:31: 3:49 error: function calls in constants are limited to struct and enum constructors [E0015]
crosscratetuple.rs:3 static ERR: othercrate::Foo = othercrate::Foo(1);
                                                   ^~~~~~~~~~~~~~~~~~
