``` fn f(x: int) -> int { x } static mut F: extern fn(x: int) -> int = f; fn main() { unsafe { F(1) } } ``` ``` error: internal compiler error: Cannot translate def def_static({crate: 0, node: 23}, true) to a callable thing! ``` Seems to have been resolved a while ago (#4523), but is still occurring. @Aatch has said this should be an easy fix, it just needs to be done. This is important for the [OpengGL function loader](https://github.com/bjz/gl-rs/tree/master/generator).
