When trying to comile a lib with with a binary (main.rs or in examples forlder), I get this error :

Could not compile `rgil`.

Could you provide some source code? If you are using associated types, this could be #18048 (ICE: When cross-crate importing trait with associated types)

[BigEpsilon]

Yes it comes from associated types, and the bug seems to be exactly the same as the one you poited out, sorry for the duplicate.

The simplified code :
src/core/point2.rs

pub trait Point2D {
    type value_type;
}

src/lib.rs

#![feature(associated_types)]

pub mod core;

src/core/mod.rs

pub mod point2;

and src/main.rs:

extern crate rgil;

use rgil::core::point2::Point2D; 

fn main(){
}

Commenting the line type value_type; removes the crash

[dylanmckay]

I'm running into this issue as well.

Dupe of #18048 which was closed on 2014-12-30. @steveklabnik would you please close this?
