Возможно ли включить _LIBCPP_DEBUG2 в текущем наборе инструментов Xcode 4.6.1 на Mountain Lion?

Эта тема является ранним обсуждением режима отладки для libc ++ clang, который должен был быть включен путем определения _LIBCPP_DEBUG2 в команде компилятора. Только что закончил бой с неправильно распределенным std::vector<> Я заинтересован в возможности включить это для моих отладочных сборок.

Когда я пытаюсь просто добавить _LIBCPP_DEBUG=1 к Макросы препроцессора настройки сборки, я получаю ошибки во время фазы соединения (показано ниже). Я подозреваю, что это вызвано вновь созданными ссылками на база данных отладки описано в ветке обсуждения.

В этом раннем обсуждении было заявлено, что необходимая поддержка присутствовала в стандартной версии библиотеки, но сегодня, похоже, это не так. Это все еще поддерживается вообще? И если да, то как мне связать нужные биты?
