--- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Reduced.  Nothing MSP430-specific here.

template <typename> struct A;
struct B {
  typedef A<int> type;
};
template <typename T> struct A { static const T max = 1 ? 1 << (T) -1 : 0; };
template <typename T> const T A<T>::max;
class F {};
template <int N> void operator>(F, int) { static_assert(N <= B::type::max); }
