OK. Here is the incriminated part of the main :

void Main_MPP( void )
{
    boost::shared_ptr<OGRRectangle> rect( new OGRRectangle(5.,TPoint2D
<double>(50.,20.),0.1325) );
    boost::shared_ptr< rectangle_with_profile<OGRRectangle> > r( new
rectangle_with_profile<OGRRectangle> ( rect , 5 , 12 , 1.5 , EXTREME) );
    //OGRRectangle destructor is call here ...
    r->DisplayConsole();
}

Here is the OGRRectangle class :

class OGRRectangle : public OGRPolygon
{
public:
    OGRRectangle() {};
    OGRRectangle( const double &width , const TPoint2D <double> &center ,
const double &angle=0. );
    OGRRectangle( const TPoint2D <double> &center , const double &width ,
const double &height , const double &angle=0. );
    OGRRectangle( const TPoint2D <double> &TopLeft , const TPoint2D <double>
&BottomRight , const double &angle=0. );
    ~OGRRectangle() {SORTIEMESSAGE("Destruction OGRRectangle
..."<<std::endl);};

    void Init( const TPoint2D <double> &center , const double &width , const
double &height , const double &angle=0. );

    inline void GetWidth( double &width ) {width=m_width;}
    inline double GetWidth() {return m_width;}
    inline void GetHeight( double &height ) {height=m_height;}
    inline double GetHeight() {return m_height;}

    void Translate( const TPoint2D <double> &trans );
    void Translate( const double &x , const double &y );
    void Rotate( const double &angle );

protected:
    double m_width;
    double m_height;
    double m_angle;
};

// Implementation

void OGRRectangle::Init( const TPoint2D <double> &center , const double
&width , const double &height , const double &angle )
{
    m_width = width;
    m_height = height;
    m_angle = angle;

    boost::shared_ptr<OGRPoint> pt( new OGRPoint );
    boost::shared_ptr< OGRLinearRing > lr( new OGRLinearRing );

    pt->setCoordinateDimension(2);
    pt->setX( center.x-0.5*width );
    pt->setY( center.y-0.5*height );
    pt->setZ( 0. );
    lr->addPoint( pt.get() );
    pt->setX( center.x+0.5*width );
    pt->setY( center.y-0.5*height );
    lr->addPoint( pt.get () );
    pt->setX( center.x+0.5*width );
    pt->setY( center.y+0.5*height );
    lr->addPoint( pt.get() );
    pt->setX( center.x-0.5*width );
    pt->setY( center.y+0.5*height );
    lr->addPoint( pt.get() );
    this->addRing( lr.get() );
    lr->setCoordinateDimension(2);
    this->setCoordinateDimension(2);

    this->closeRings();

    if ( m_angle != 0. )
        Rotate(m_angle);
}

OGRRectangle::OGRRectangle( const double &width , const TPoint2D <double>
&center , const double &angle )
{
    Init(center,width,width,angle);
    setCoordinateDimension(2);
}

OGRRectangle::OGRRectangle( const TPoint2D <double> &center , const double
&width , const double &height , const double &angle)
{
    Init(center,width,height,angle);
    setCoordinateDimension(2);
}

OGRRectangle::OGRRectangle( const TPoint2D <double> &TopLeft , const
TPoint2D <double> &BottomRight , const double &angle)

{
    double width = abs(BottomRight.x - TopLeft.x);
    double height = abs(BottomRight.y - TopLeft.y);
    Init(0.5*(TopLeft+BottomRight),width,height,angle);
    setCoordinateDimension(2);
}

Courage.
