<pre>#include <new>
struct b {
virtual ~ b() {}
};
struct d : b {
~ d () {}
};
int main() {
d o;
o.~b();
new( & o ) d;
}
This is well formed but gets a diagnosis "destructor type 'b' in object
destruction expression does not match the type 'd' of the object being
destroyed".
The most applicable rule is §12.4/13:
… if the object is not of the destructor’s class type and not of a class
derived from the destructor’s class type (including when the destructor is
invoked via a null pointer value), the program has undefined behavior.</pre>
