The following invalid code snippet triggers an ICE on mainline:

================================================================
template<typename...> class A {};

template<int> class A<> {};

template<typename T, typename...U> struct A<T,U...> : A<U...>
{
  A() {}
};

A<int> a;
================================================================

bug.cc:3: error: template parameters not used in partial specialization:
bug.cc:3: error:         '<anonymous>'
bug.cc: In constructor 'A<T, U ...>::A() [with T = int, U = ]':
bug.cc:10:   instantiated from here
bug.cc:7: internal compiler error: in build_simple_base_path, at cp/class.c:489
Please submit a full bug report, [etc.]
