Ah yes of course, otherwise destructor would work on a deleted object
... test code ...

#include <iostream>

struct X {
    X () { std::cout << "ctor\n"; }
    ~X () { std::cout << "dtor\n"; }
    void operator delete (void * s) { std::cout << "delete\n"; free (s); }
    void* operator new (size_t s) { std::cout << "new\n"; return malloc (s); }
};

int main () {
    X * x = new X;
    delete x;
    return 0;
}

$ g++  tor.cpp
$ ./a.out
new
ctor
dtor
delete

Oh well, who needs test code if one can reason :-)
