// Check that virtual destructors work correctly. Specifically,
// check that when you destruct an object of a derived class for
// which the base class had an explicitly declared virtual destructor
// no infinite recursion occurs.
//
// Bug description:
// The generated g++ code apparently calls the base class destructor via
// the virtual table, rather than directly. This, of course, results in the
// infinite recursion.
