Details:

/** Free a tcp listen pcb */
static void
tcp_free_listen(struct tcp_pcb *pcb)
{
  LWIP_ASSERT("tcp_free_listen: !LISTEN", pcb->state != LISTEN); *<----here it
should be pcb->state == LISTEN *
#if LWIP_TCP_PCB_NUM_EXT_ARGS
  tcp_ext_arg_invoke_callbacks_destroyed(pcb->ext_args);
#endif
  memp_free(MEMP_TCP_PCB_LISTEN, pcb);
}

this might cause resource leak.
