Destructors are not executed for when static variables are cleared and it's intentional design decision. Class definition in Harbour are stored in static variables so if we enable destructor execution for static variables the we introduce very serious limitation because at this moment some class may not exists and it's necessary to document that it's illegal to use any code which may create new object inside destructors. Such situation is now in xHarbour and I can only guess that author never thought what he really does. To enable destructors for static variables we should 1-st change our class code to protect class objects against releasing before destructors are executed. Maybe I'll make it in the future. Now it's documented behavior that at HVM quit state PRG destructors are disabled just before releasing static variables so programmer does not have to worry that application may crash if he activates OOP code for class released before. best regards, Przemek _______________________________________________ Harbour mailing list Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
