+// object without a virtual destructor.
+//
+// Diagnostic flags -Wnon-virtual-dtor and -Wdelete-non-virtual-dtor report if
+// an object with a virtual function but a non-virtual destructor exists or is
+// deleted, respectively.
+//
+// This check exceeds them by comparing the dynamic and static types of the
+// object at the point of destruction and only warns if it happens through a
+// pointer to a base type without a virtual destructor. The check places a note
+// at the last point where the conversion from derived to base happened.
