Unexpected failure, when interfacing with C code

[nickik]

I am trying to write a interace to some C Code, the interface code was generated by bindgen-rust.

pub static MPS_KEY_ARGS_END: mps_key_t = &_mps_key_ARGS_END; //code I added

pub enum Struct_mps_key_s { }
pub type mps_key_t = *const Struct_mps_key_s;

extern "C" {
        pub static _mps_key_ARGS_END: Struct_mps_key_s;
}   

System: Arch Linux x86

Rust version:
aur/rust-nightly-bin 0.13.0_2014.10.27-1 (16)
A safe, concurrent, practical language from Mozilla.

This line seams to make the diffrence:
pub static MPS_KEY_ARGS_END: mps_key_t = &_mps_key_ARGS_END; //code I added

if I comment it out, the compiler runs without error.

Minimal test case:

extern "C" {
    static A: int;
}

static B: int = A;

Unable to repro:

extern "C" {
    static A: i8;
}

static B: i8 = A;

fn main() {
    // Add code here
}

$ rustc main.rs
