During discovery of owned devices, a crash is produced when IoTivity-lite sends a GET request to "/oic/res?rt=oic.r.doxm" to get the endpoints.
 
As the attached log file of IoTivity-lite shows, the OBT discovers an unowned device (Device ID: 1687423f-e096-4034-69c1-d492c399a974) and it can get the endpoints successfully. Then, the OBT discovers an owned device but when it tries to get the endpoints, IoTivity-lite throws the following crash caused by a null pointer dereference:
