  This problem occurred on the following conditions.
  
   1.The active SDEP CIs wrap around the end of the area.
   2.The SDEP segment, which is pointed by SPCF pointer in root
     segment of the problem, has been deleted logically by DEDB
     Delete Utility and the RBA of it is between SDEP start RBA
     and LE.
  

Problem conclusion

• The target database is above conditions, the pointer errors
  causes by RELOAD with SDEPRELOCATE=YES.
  This problem is caused because the RELOAD process do not
  consider the cycle counter of SPCF pointer.
  
  The module FABC3SDX is modified to clear SPCF pointer, when
  SDEP pointer is smaller than LB pointer in consideration of
  cycle count.
