Duplicated Bug 29909 also points out the not-so-obvious case where the
overridden virtual method is actually the automatically-compiler-generated
derived class destructor:

// compile with g++ -Wall -O

class one {
public:
        virtual __attribute((regparm(3))) ~one();
};

class two : public one {
};

int main() { 
        one * o = new two();                                                   
                                                                        delete
o;                                                                             
                                                         return 0;             
                                                                               
                                   }

Still looks like a valid issue.
