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.
