This would be a bug in etharp.c or ip_addr_*(). Please see why your IP
addresses
would fall through this if statement:

---
update_arp_entry()

  /* non-unicast address? */
  if (ip_addr_isany(ipaddr) ||
      ip_addr_isbroadcast(ipaddr, netif) ||
      ip_addr_ismulticast(ipaddr)) {
    LWIP_DEBUGF(ETHARP_DEBUG | DBG_TRACE, ("update_arp_entry: will not
    add non-unicast IP address to ARP cache\n"));
    return ERR_ARG;
  }
---
