ICE: Cannot relate bound region

[eholk]

Trying to compile the following program generates an internal compiler error.

pub struct SubMatrixView<'r, M>;

trait SubMatrix<'r, Base> {
    fn submatrix(&'r self) -> SubMatrixView<'r, Base>;
}

fn sub<'r, T, M: SubMatrix<'r, M>>(M: &'r M)
    -> SubMatrixView<M>
{
    M.submatrix();
}

fn main() {
}

The error message is:

test.rs:10:4: 10:5 error: internal compiler error: Cannot relate bound region: ReLateBound(20, BrNamed(syntax::ast::DefId{crate: 0u32, node: 37u32}, r)) <= ReInfer(3)
This message reflects a bug in the Rust compiler. 
We would appreciate a bug report: https://github.com/mozilla/rust/wiki/HOWTO-submit-a-Rust-bug-report
test.rs:10     M.submatrix();
