Re: Segfault on Gtk::ListStore::clear ()

[Kjell Ahlstedt <kjellahlstedt gmail com>]

I added some code to one of the example programs in gtkmm-tutorial,
https://gitlab.gnome.org/GNOME/gtkmm-documentation/-/tree/gtkmm-3-24/examples/book/combobox/complex

ExampleWindow::~ExampleWindow()
{
  Gtk::TreeIter iList = m_refTreeModel->get_iter("0");
  while (iList)
  {
    std::cout << (*iList)[m_Columns.m_col_name] << std::endl;
    ++iList;
  }
  m_refTreeModel->clear();
}

No segfault!

You should use a debugger, such as gdb, to find out where the segfault 
is generated.
