は、実行時にアクセス違反をスローする小さなスニペットです。ラインでアクセス違反がブーストファイル「socket_ops.ipp」で発生しているブーストソケットAsync_Connectアクセス違反
m_socket.async_connect(end_point, yieldw[ec]);
を呼び出すときに、私は、Visual Studio 2015およびブースト1.60.0とを
"socket_type s = error_wrapper(::WSASocketW(af, type, protocol, 0, 0,WSA_FLAG_OVERLAPPED),ec);"
例外は、「未処理されて使用していますConsoleApplication4.exeの0x000007FEFD598A2F（KernelBase.dll）の例外：0xC0000005：アクセス違反が0xFFFFFFFFFFFFFFFFの場所を読み取っています。
