+// Test multiple inheritance with and without virtual bases.

+// Details:
+// - Test multiple inheritance with virtual bases. Using a virtual

+// to the "consumer" object. Verify that results are as expected.
+// - Test multiple inheritance without virtual bases. Using a non-
+// virtual base class, copy one or more strings from the "producer" 
+// object to the "consumer" object. Verify that results are as expected.
