[Bug c++/16514] New: no warning of non-virtual dtor in subclass

[naiman at math dot jct dot ac dot il]

Dear G++ Folk,

An astute student found the following example:

vvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
class foo1 {
public:
    virtual void f1 (void) {}
    virtual ~foo1 (void);
};

class foo2 : public foo1 {
public:
    ~foo2 (void);
};
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

We believe the compiler should at least warn that foo2
has a virtual function, and non-virtual dtor.

Thank you for your time!

ATB,

Aaron Naiman
