         * itk/generic/itk_archetype.c (ArchComponent, Itk_ArchCompDeleteCmd,
        Itk_CreateArchComponent, Itk_DelArchComponent): Save a copy
        of the window path name in the ArchComponent struct and use
        it in the Itk_ArchCompDeleteCmd method. The old code was
        invoking Tk_PathName(tkwin) on a Tk_Window which lead to
        a memory access on memory that has already been free'd
        when the widget was destroyed.
