'destructor' : override specifier 'keyword' not allowed on a destructor/finalizer

A keyword was used that is not allowed on a destructor or finalizer.

For example, a new slot cannot be requested on a destructor or finalizer. For more information, see Explicit Overrides and Destructors and Finalizers.

The following sample generates C3665:

// C3665.cpp
// compile with: /clr
public ref struct R {
   virtual ~R() { }
   virtual void a() { }
};

public ref struct S : R {
   virtual ~S() new {}   // C3665
   virtual void a() new {}   // OK
};
