Description: Apparently, the variable NOCLEARSTKLST is a dotted list whose CAR''s are stack ptrs and whose last CDR is the atom NOBIND (pretty susipicious).  When I have CAR/CDRERR = CDR, I am unable to ↑D because there is a form containing (FMEMB X NOCLEARSTKLST) on RESETFORMS.  FMEMB will break because of the dotted list passed to it.
