[gtkada] Fwd: Gtk.List_Store.Swap

[Jan de Kruyf]

Hallo,
I seem to have a funny I cannot resolve:

'Gtk.List_Store.Swap' breaks as follows:
-------------------------------------------------------------------
 Execution terminated by unhandled exception
Exception name: STORAGE_ERROR
Message: stack overflow (or erroneous memory access)
Call stack traceback locations:
0x7fb4957224ee 0xfffffffffffffffe
-------------------------------------------------------------------
addr2line gives no answers.

However, both the model and the iters are valid as far as I can see.
Here is a snippet of the code:
--------------------------------------------------------------------
      Model        : Gtk.List_Store.Gtk_List_Store;
--Gtk.Tree_Model.Gtk_Tree_Model;
      Path1, Path2 : Gtk.Tree_Model.Gtk_Tree_Path;
      Iter1, Iter2 : Gtk.Tree_Model.Gtk_Tree_Iter;

begin
.
.
.
-- initialization of 'Model'
      Gtk.Tree_Selection.Get_Selected_Rows
    (Selection => Selection,
     Model     => Gtk.Tree_Model.Gtk_Tree_Model (Model),
     Path_List => Rows);
.
.
-- iters are found
.
.
-- test code, which gives correct results:
        Info_Message (Gtk.Tree_Model.Get_String
(Gtk.Tree_Model.Gtk_Tree_Model (Model), Iter1, 0));
        Info_Message (Gtk.Tree_Model.Get_String
(Gtk.Tree_Model.Gtk_Tree_Model (Model), Iter2, 0));
-- immediately followed by the offending statement:
        Gtk.List_Store.Swap
          (Store   => Model,
           A       => Iter1,
           B       => Iter2);
.
.
end
--------------------------------------------------------------------------------------------

I hope one of you might have some time to help me here, thanks.
