 Tell me how options.bind_address can reach getaddrinfo() as null. As I
see it there is no possible way it can happen.

[..]
      /* Bind the socket to an alternative local IP address */
        if (options.bind_address == NULL)
                return sock;

        memset(&hints, 0, sizeof(hints));
        hints.ai_family = ai->ai_family;
        hints.ai_socktype = ai->ai_socktype;
        hints.ai_protocol = ai->ai_protocol;
        hints.ai_flags = AI_PASSIVE;
        gaierr = getaddrinfo(options.bind_address, "0", &hints, &res);
