Override identifier after destructor in C++11

Question

Does the override identifier after virtual destructor declaration have any special meaning?

class Base
{
public:
    virtua         


        

Answer 1

It is not override that has special meaning, but the destructor itself:

10.3 Virtual Functions

6/Even though destructors are not inherited, a destructor in a derived class overrides a base class destructor declared virtual; see 12.4 and 12.5.

If you take this in conjunction with the previous clause:

5/If a virtual function is marked with the virt-specifier override and does not override a member function of a base class, the program is ill-formed. [ Example:

struct B { 
    virtual void f(int); 
}; 

struct D : B
{ 
    void f(long) override; // error: wrong signature overriding B::f
    void f(int) override; // OK 
}; 

—end example ]

you can see that if a destructor is marked override but the base class does not have a virtual destructor, the program is ill-formed.
