Hi, sometimes throw exception and function CUCListener::OnAccept? not called when connected

socket_ops.ipp

socket_type socket(int af, int type, int protocol,
    boost::system::error_code& ec)
{
  clear_last_error();
#if defined(BOOST_ASIO_WINDOWS) || defined(__CYGWIN__)
  socket_type s = error_wrapper(::WSASocketW(af, type, protocol, 0, 0,
        WSA_FLAG_OVERLAPPED), ec); // Exception Throw
  if (s == invalid_socket)
    return s;
...
}
