Hi, I had a look to these two PRs and, as regards the former, the below patchlet seems Ok to me even for 4.8.1. About the latter: a similar change works fine for std::vector and std::deque, but std::list for example has another problem, which is already exposed by the v1.emplace_back(i); bit and seems unrelated: we have: template<typename _Tp> struct _List_node : public __detail::_List_node_base { ///< User's data. _Tp _M_data; #if __cplusplus >= 201103L template<typename... _Args> _List_node(_Args&&... __args) : __detail::_List_node_base(), _M_data(std::forward<_Args>(__args)...) { } #endif }; together with: template<typename... _Args> _Node* _M_create_node(_Args&&... __args) { _Node* __p = this->_M_get_node(); __try { _M_get_Node_allocator().construct(__p, std::forward<_Args>(__args)...); } __catch(...) { _M_put_node(__p); __throw_exception_again; } return __p; } and this is not Ok in terms of access control, because _List_node tries to use the constructor, not the allocator (not sure how strict the Standard is in terms of access control) I guess we could at least work around the problem by going back to _M_get_Tp_allocator().construct in _M_create_node (or, better, the allocator_traits<>::construct equivalent, per the recent fix for 56613; we would use it on _Tp actually, everywhere) but I don't know if Jon has already something in his tree for this batch of issues regarding our base container class / node constructors, or we want to decouple the issue from 55977, do std::vector and std::deque, which would be trivial even for 4.8.1, or something else. Suggestions? Thanks!
