[Bug c++/36642] New: Problem with non matching template args in tr1_impl/hashtable

["jeff dot sullivan at intel dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I think there may be two issues here demonstrated in the code below. The
example code is distilled from ./include/c++/4.3.0/tr1_imp/hashtable. GCC
compiles this code without a diagnostic, but both the Intel and Microsoft
compilers diagnose an error with too few template args for __detail::_Map_base'
:

% cl -c t.cpp -nologo
t.cpp
t.cpp(10) : error C2976: '__detail::_Map_base' : too few template arguments
        t.cpp(4) : see declaration of '__detail::_Map_base'

% cat t.cpp
namespace __detail
{
  template<typename _Key, typename _Value, typename _Ex, bool __unique,
    typename _Hashtable> struct _Map_base { };
}

struct  _Hashtable
{
  template<typename _Key2, typename _Pair, typename _Hashtable>
  friend struct __detail::_Map_base;
};

So, you may want to fix the template in <tr1_imp/hashtable> and/or try to
diagnose this case in the compilation.
