* The first example doesn't compile (`virtual void ~Base();`)
* The example also produces a clang-analyzer-cplusplus.NewDelete warning, which might lead to confusion
A better example could be
~~~c++
struct Base {
virtual ~Base();
int i;
};
struct Derived : public Base {};
int foo(const Derived d[]) {
return d[1].i;
}
~~~
In this case, making `Derived` `final` suppresses the warning.
