[Bug c++/13810] New: [3.4/3.5 Regression] ICE on default templates

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I do not know if this is valid or invalid code but it still ICEs and it is a regression from 
3.3.3.  I found this while trying to reduce PR 13809.

namespace std
{
template<typename> struct less{};
template<typename> struct allocator{};
template<typename A, template<typename> class B = std::less<A>,
  template<typename> class C = std::allocator<A> > struct set{};
}
