6  PROBLEMS ADDRESSED IN ALPDEBU02_062 KIT


      o  The  ALPDEBU01_062  remedial  kit  stated  that  there  was   a
         dependency   on   ALPLIBR07_062.    This  was  incorrect.   The
         dependency is on remedial kit ALPY2K01_062.  There are  no  new
         problem   fixes  in  this  kit.   If  you  have  installed  the
         ALPDEBU01_062 remedial kit, you do not  need  to  install  this
         kit.



7  PROBLEMS ADDRESSED IN ALPDEBU01_062 KIT


      o  DEBUG  links  LIBRTL.OLB  into  its   DEBUG.EXE   image.    The
         LIB$CALLING_STANDARD  routines  included can ACCVIO when trying
         to walk the call chain or write to a call's invocation  context
         block on a corrupt stack.  These ACCVIOs have now been observed
         from DEBUG CALL commands from certain register frames.

         In order to receive this full fix,  the  ALPY2K01_062  remedial
         kit must also be installed.



8  PROBLEMS ADDRESSED IN ALPDEBU01_071 KIT FOR OPENVMS ALPHA V6.2*


      o  Build the debugger against Motif V1.2-3 and provide workarounds

         at  any  point  and  then executing the RERUN command causes an
         ACCVIO.

      o  On startup, DEBUG occasionally fails with ACCVIO on some  ALPHA
         programs.



12  PROBLEMS ADDRESSED IN ALPDEBU01_070 KIT FOR OPENVMS ALPHA V6.2*


      o  RFA, Record File  Address,  tables  were  sometimes  not  being
         properly  updated.   The conditional that helped determine when
         to update was depending on  a  variable  that  it  assumed  was
         static, but was, instead, changing dynamically.
