Hello,

I think I found BUG. 
Let we have this program: 
- -- cut here --
#include <boost/shared_ptr.hpp>
#include <boost/weak_ptr.hpp>
#include <boost/intrusive_ptr.hpp>
#include <cstdio>

using namespace std;

#define INTR

class MujObjekt
#ifdef INTR
: public boost::counted_base
#endif
{	
public:
        MujObjekt()
        {
                printf( "MujObjekt::MujObjekt()\n" );
        }

        void setThis( boost::shared_ptr<MujObjekt> obj )
        {
                m_this = obj;
        }

        virtual ~MujObjekt()
        {
                printf( "MujObjekt::~MujObjekt()\n" );	
        }

        boost::weak_ptr<MujObjekt> m_this;
};

int main()
{
        boost::shared_ptr<MujObjekt> obj( new MujObjekt() );
        obj->setThis( obj );

        return( 0 );
}
- --- cut here ---

But in case of usage of intrusive pointer it doesn't call destructor - because 
there is weak pointer.

But when I undefine INTR and it uses non-intrusive it works as expected. This 
is only modelling case to simulate bug.
