	Yes, I have ;-)

	Please try to launch RPL/2 with rpl -is. I think you shouldn't receive 
a stack overflow error. Where have you downloaded sources ? This very 
minor bug (segfault when a child process ends) was fixed a long time 
ago. I have verified that it is fixed in 4.0.0.prerelease.2 on the 
official web page.

	You can check too that src/encart.c ends by :

             XmDestroyPixmap(XtScreen(popup), pixmap_rpl);
             XmDestroyPixmap(XtScreen(popup), pixmap_rpl_masque);

             XtDestroyWidget(pixmap);
             XtDestroyWidget(cadre);
             XtDestroyWidget(form);
             XtDestroyWidget(popup);
             XtDestroyWidget(objet_principal);

             if (sigaction(SIGINT, &action_passee, NULL) != 0)
             {
                 (*s_etat_processus).erreur_systeme = d_es_signal;
                 return;
             }

             exit(0);
         }
         else
         {
             if (sigaction(SIGINT, &action_passee, NULL) != 0)
             {
                 (*s_etat_processus).erreur_systeme = d_es_signal;
                 return;
             }

             (*s_etat_processus).erreur_systeme = d_es_signal;
             return;
         }
     }
#   endif

     return;
}

// vim: ts=4

	That being said, it is possible you have found a new bug. In this case, 
you can start RPL/2 with (of course in bash ulimit -c unlimited) rpl -id 
to avoid signal management.
