[Freeciv-Dev] Re: (PR#5095) client-xaw crashes when opening city dialog (1.14.0)

Hi!

Unfortunately, I don't know how to make a backtrace. However, I guess I 
could solve the issue myself, patching create_city_dialog (in 
citydlg.c). There are a couple of calls to fc_malloc, so I tried to 
wrap some error checking around that. Funny indeed, fc_malloc does that 
already. Well, it works outs for me.

Best wishes,
   Diedrich

pdialog=fc_malloc(sizeof(struct city_dialog));
if (pdialog)
{
   // code goes here...

   pdialog->citizen_labels=
     fc_malloc(pdialog->num_citizens_shown * sizeof(Widget));
   // some further calls to fc_malloc...

   if ( pdialog->citizen_labels && pdialog->citizen_type
        && pdialog->support_unit_pixcomms &&
        pdialog->present_unit_pixcomms )
   {
     // code goes here
   }
}
