BTW, this is C++14 code, what's wrong with:

 template<typename _Kt>
   std::pair<const_iterator, const_iterator>
   equal_range(const _Kt& __x) const
   {
     auto __res = _Base::equal_range(__x);
     return { iterator(__res.first, this), iterator(__res.second, this) };
   }

Or even:

 template<typename _Kt>
   std::pair<const_iterator, const_iterator>
   equal_range(const _Kt& __x) const
   {
     auto __res = _Base::equal_range(__x);
     return { { __res.first, this }, {__res.second, this} };
   }
