>Description:
The following snippet gives misleading warnings and an ICE:
template<class T> class smart_ptr2 {
    T* real_ptr;
 public:
    typedef typename T::subT  td;
    friend class td;
};

There is a real error in this code: it's illegal to use an elaborated-type-specifier with a typedef name.  (7.1.3, paragraph 4, and 7.1.5.3.)  However, an ICE is not the friendliest diagnostic.

The ICE is in pop_binding.
