Crash in QMenu::exec() or QMenu::popup()

I have got an crash when the mouse hovers over a submenu for a QOpenGLWidget. It happens occasionally when I right-click the window continually.

Code example:

void tWidget::contextMenuEvent(QContextMenuEvent * event)
{
    QMenu menu;    
      menu.addAction(action0);
    menu.addAction(action1);    
      QMenu * submenu0 = menu.addMenu("submenu0");
    submenu0->addAction(action2);
    submenu0->addAction(action3);    
      QMenu * submenu1 = menu.addMenu("submenu1");
    submenu1->addAction(action4);
    submenu1->addAction(action5);    
      menu.exec(event->globalPos());
}
