boost::asio::async_write вызывает Segmentation fault
Приветствую.
Даже спрашивать уже опасаюсь, опять отдельные личности с большим самомнением начнут объяснять какой я тупой, но все таки попробую, вдруг кому не сложно )
Код класс ниже, теста ради из одного потока все работало, пока не решил вызвать CPush::Send из другого и все упало. Думал сначала что дело в std::stringstream request, которая была локальная - поднял ее до класса и не помогло.
Хоть намек бы к пониманию, где косяк, заранее спасибо за не равнодушие )
