[Bug c++/20157] New: Internal compiler error on invalid code

[sstrasser at systemhaus-gruppe dot de]

4.0.0 outputs internal compiler error on the following invalid code.
3.3/3.4 silently ignores it.

if the invalid template function specialization is a definition 3.3/3.4
correctly reports it, 4.0.0 still outputs an internal compiler error.

template<typename AT>
struct A{
  template<typename T>
  void function(T);
};

template<>
template<typename ABC,typename DEF>
void A<int>::function(ABC);
