Problem summary

• APAR NUMBER:  PJ41041
  PRODUCT:  z/TPF
  FUNCTIONAL AREA:  DEBUG TOOL SUPPORT
  SHIPPED IN PUT:  10
  
  ABSTRACT:
  An CTL-1 dump may occur because the debugger logic to copy the
  breakpoint table does not switch to 64 bit mode before calling
  MOVEC.
  
  PACKAGE CONTENTS:
  Source Segments:
  (C) base/cp/cudr.cpy
  
  Object Only Binaries:
  None.
  
  Configuration Independent Binaries:
  None.
  
  Support Files:
  None.
  
  OTHER BINARIES TO BUILD: YES
  (C) <sys>/obj/ccvage.o
  (C) <sys>/load/CPS0.so
  
  COMMENTS:
  This problem occured because of the following sequence of
  events.
  CUDU_CK_PER calls CPERMERG, which calls CUDRCOPY, which calls
  MOVEC. The MOVEC code routine calls GSWBC.
  
  In CCSTOR, GSWBC processing causes the CTL-1.
  Register 8 is set up from PBTDEL. But PBTDEL contains zero's.
  As a result, SCT#GETR2 does not have a valid value.
  The PBTDEL field in the IDSPBT structure has been overwritten.
  This storage was overwritten because the logic in the CP
  assumes 64 bit mode, but we are really in 31 bit mode.
  

Problem conclusion

• SOLUTION:
  The CUDRCOPY logic in segment cudr.cpy has been updated to
  always be in 64 bit mode.
  
  COREQS: NO
  None.
  
  MIGRATION CONSIDERATIONS: NO
  None.
  
  BUILD COMMANDS AND INSTRUCTIONS: YES

  UPDATED INFORMATION UNITS: NO
