+puts "OCC31320"

Could you please add a full bug description to the test? E.g.
+puts "0031320: TObj - method TObj_Object::GetFatherObject() is not protected against deleted object"

   Handle(TObj_Object) aFather, aSon(this);
 
+  if (myLabel.IsNull())
+    return aFather;

tip: maybe it would be better moving this check before creating an unused aSon(this) handle...
