The "name" field (the 1st parameter) in your heur_dissector_add() call is not valid. Or I suppose it may be valid but you're calling heur_dissector_add() before the other protocol has been registered (are you calling heur_dissector_add() in your reg_handoff routine?).

void proto_reg_handoff_arr(void)

{

static gboolean initialized=FALSE;

if (!initialized) {


arr_handle = new_create_dissector_handle(dissect_arr, proto_arr);

dissector_add_handle(“tcp”, arr_handle);

    heur_dissector_add("tcp", dissect_arr_heur, proto_arr);


}

}

this is the code
