Err, no, it doesn't. Sheesh, and to say that the EPITA is renowed as a 
school for the high-tech elite :-).

Another typical one, harder to track and easier to do :

class MyWidget
{
...

Gtk_VBox m_vbox;
};

MyWidget::MyWidget()
{
  Gtk_Button myButton("a button");

  m_vbox.pack_start(myButton);
}


myButton will be destroyed on exit of the ctor.
