--- Comment #1 from Volker Reichelt <reichelt at gcc dot gnu.org> ---
Confirmed. ICEs since GCC 4.7.0.

Here's a testcase without variadic templates:

============================================
template<int> struct A
{
  virtual ~A();
};

template<typename> struct B : A<0>, A<1>
{
  ~B() = default;
};

struct C : B<bool>
{
  C() {}
};
============================================
