--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to rylai from comment #0) > As we can see, std::list implementation tries to call construct for whole > list node (U = std::_List_node<int>), This is already fixed on the SVN trunk, which will be GCC 5. > and std::set and map (and also > multiset and multimap) call it for right type (int or std::pair<const int, > int>), but from rebinded allocator (T = std::_Rb_tree_node<int>). I've discussed this extensively with the main author of the C++11 allocator proposals and other members of the committee. The standard is supposed to allow that, the fact it doesn't is a defect, see http://cplusplus.github.io/LWG/lwg-active.html#2218
