 int main()
{
  boost::intrusive_ptr<X> px(new X);  // obj's internal count=1
  boost::intrusive_ptr<X> px2(px); // obj's internal count=2
  boost::shared_ptr<X> px3(px2); // obj's internal count still =2, detached
count=1

  px = 0; // obj's internal count=1
  px2 = 0; // obj's internal count=0  -----> obj suicides itself....

*px3 ;  // undefined behavior, pointee no longer alive.
 }

What I am missing?
