Hi,

Well the bug is in the fact the when you allocated:
    B* b = new X();

You have allocated an int extra, thus when you call:
    delete b;

You are only destructing what was allocated by B, which cause a sizeof(int) bytes memory leak each time you do this.

Just use a virtual destructor on virtual ~B() ... and that would take care of it all.

With best regards
