+# Checks : Member variable deleted incorrectly.
+#
+# Reason : When a member variable is deleted, it should be assigned
+# either to NULL or to another value. This prevents accidental
+# access of the deleted object. If a NewL() or other leaving
+# function is called to reassign the member variable, it should
+# first be assigned to NULL in case that function leaves.
