Follow-up Comment #14, bug #21272 (project freeciv):

Thanks.

...and again, common suffix starts at gdk_window_new() and what's below that
is different.

Here's the decode for the bit of Freeciv code in the middle:


...
0FB01DC  C:\MyGames\Freeciv\libgtk-win32-2.0-0.dll:00FB01DC  gtk_widget_show
00FBE2F1  C:\MyGames\Freeciv\libgtk-win32-2.0-0.dll:00FBE2F1 
gtk_window_present
00430383  _popup_unit_select_dialog
00424AD6  _do_map_click
0042E993  _butt_down_mapcanvas
00E9733A  C:\MyGames\Freeciv\libgtk-win32-2.0-0.dll:00E9733A 
gtk_marshal_VOID__UINT_STRING
63A43B7A  C:\MyGames\Freeciv\libgobject-2.0-0.dll:63A43B7A  g_closure_invoke
...


(Since this is the unit select dialog, this might have been clicking on a
team-mate's city?)

I'm reasonably willing to believe that this is a random Gtk failure with a
chance of occurring whenever a window is popped up.

Good question. From Google, I think LT30 ran from about Jan-Aug 2012, right?
The latest clients available in that period were 2.3.1 and 2.3.2; the Windows
builds might well have been using an even older version of Gtk which didn't
have the bug (but I haven't checked).

We've got no evidence that it will yet, it's just a guess. On the other hand,
I have no better ideas.
