--- Comment #3 from Reid Kleckner <rnk at google.com> ---
This appears to be different. It has to do with dependent types sneaking
through to codegen via templated friend functions (ew). Here's what I got from
reduction:

struct A {
  template <class, bool> class B {
    template <class r_colony_allocator_type, bool r_is_const,
              class distance_type>
    friend void advance(B<r_colony_allocator_type, r_is_const> &,
                        distance_type);
  };
  template <class r_colony_allocator_type, bool r_is_const, class
distance_type>
  friend void advance(B<r_colony_allocator_type, r_is_const> &, distance_type)
{
    distance_type a;
  }
};
int main() {
  A::B<int, false> b;
  advance(b, 0);
}
