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

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.
