[Bug c++/31433] New: [4.3 regression] ICE with invalid parameter pack for template struct

[reichelt at gcc dot gnu dot org]

More fallout from the variadic templates on mainline:

===========================================================
template<typename..., typename> struct A
{
  static int i;
};

A<int, int> a;
A<char,int> b;
===========================================================

bug.cc:1: error: parameter pack '<template-parameter-1-1>' must be at the end
of the template parameter list
bug.cc: In instantiation of 'A<int, int>':
bug.cc:6:   instantiated from here
bug.cc:2: error: template argument 1 is invalid
bug.cc:2: error: template argument 1 is invalid
bug.cc:3: error: template argument 1 is invalid
bug.cc: In instantiation of 'A<char, int>':
bug.cc:7:   instantiated from here
bug.cc:2: error: template argument 1 is invalid
bug.cc:2: error: template argument 1 is invalid
bug.cc:3: error: template argument 1 is invalid
bug.cc:3: internal compiler error: in finish_member_declaration, at
cp/semantics.c:2270
Please submit a full bug report, [etc.]

This is very similar to PR31432, but needs two instantiations of
the template to trigger an ICE.
