Unexpected internal compiler error fixing Any

[milibopp]

I just tried fixing the absence of Any from the prelude in the latest Rust compiler like so:

diff --git a/src/object.rs b/src/object.rs
index b76bcbf..3c2dd60 100644
--- a/src/object.rs
+++ b/src/object.rs
@@ -2,6 +2,7 @@

 use std::cell::RefCell;
 use std::rc::Rc;
+use std::any::Any;
 use gl::types::*;
 use nalgebra::na::{Mat3, Vec2, Vec3, Iso3, Rotation, Rotate, Translation, Transformation};
 use nalgebra::na;

This caused an unexpected compiler error:

error: internal compiler error: unexpected failure
This message reflects a bug in the Rust compiler. 
We would appreciate a bug report: http://static.rust-lang.org/doc/master/complement-bugreport.html
note: the compiler hit an unexpected failure path. this is a bug
Ok(task 'rustc' failed at 'index out of bounds: the len is 0 but the index is 0', /build/rust-git/src/rust/src/librustc/lib.rs:1
)

Will report upstream as well, but I thought raising an issue here is probably also a good idea, since it effectively makes compiling kiss3d impossible.

Thanks for reporting the issue.
I have fixed it, thanks to @jeremyletang.
