Infinite loop in compiler with forward reference

[Justin Johansson]

Compiling the following with latest DMD D2 sends the compiler into an
infinite loop.  The culprit line seems to be the alias definition.
Can someone else please confirm.
Thanks Justin




module test;


class Base
{
    Base foo();
}

class Foo: Base
{
    static class Bar: Foo
    {
       Bar foo() {
          return this;
       }
    }

    Bar foo();
}

alias Foo.Bar FooBar;


void main()
{
}
