api_lib.c line 203
the following code:
"
  API_MSG_VAR_REF(msg).conn = conn;
#if LWIP_SO_SNDTIMEO || LWIP_SO_LINGER
  /* get the time we started, which is later compared to
     sys_now() + conn->send_timeout */
  API_MSG_VAR_REF(msg).msg.sd.time_started = sys_now();
#else /* LWIP_SO_SNDTIMEO || LWIP_SO_LINGER */
#if LWIP_TCP
  API_MSG_VAR_REF(msg).msg.sd.polls_left =
    ((LWIP_TCP_CLOSE_TIMEOUT_MS_DEFAULT + TCP_SLOW_INTERVAL - 1) /
TCP_SLOW_INTERVAL) + 1;
#endif /* LWIP_TCP */
#endif /* LWIP_SO_SNDTIMEO || LWIP_SO_LINGER */
  err = netconn_apimsg(lwip_netconn_do_delconn, &API_MSG_VAR_REF(msg));
  API_MSG_VAR_FREE(msg);
"

should be :

"  API_MSG_VAR_REF(msg).conn = conn;

#if LWIP_TCP
#if LWIP_SO_SNDTIMEO || LWIP_SO_LINGER
  /* get the time we started, which is later compared to
     sys_now() + conn->send_timeout */
  API_MSG_VAR_REF(msg).msg.sd.time_started = sys_now();
#else /* LWIP_SO_SNDTIMEO || LWIP_SO_LINGER */
  API_MSG_VAR_REF(msg).msg.sd.polls_left =
    ((LWIP_TCP_CLOSE_TIMEOUT_MS_DEFAULT + TCP_SLOW_INTERVAL - 1) /
TCP_SLOW_INTERVAL) + 1;
#endif /* LWIP_SO_SNDTIMEO || LWIP_SO_LINGER */
#endif /* LWIP_TCP */
  err = netconn_apimsg(lwip_netconn_do_delconn, &API_MSG_VAR_REF(msg));
  API_MSG_VAR_FREE(msg);"
