The following valid code causes segfault with GCC 4.8.0 20120916 and GCC 4.7.3
20120922.

///////////////////////////////////////////////////////////
template <typename T>
struct base {
  typedef base base_type;
};

template <typename T>
struct derived : base<T> {
  typedef typename derived::base_type::base_type base_type;
  derived() : base_type() {}
};

Note that the above code compiles successfully with GCC 4.6.4 20120921.
