Problem summary

  • APAR NUMBER:  PJ41111
    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  SYSTEM ERROR AND RECOVERY
    SHIPPED IN PUT:
    
    ABSTRACT:
    The C function SERRC_OP_EXT may cause the dump number to change
    when the number of serrc_list items exceeds 9.
    
    PACKAGE CONTENTS:
    Source Segments:
    (C) base/rt/cserrc.asm
    
    Object Only Binaries:
    None.
    
    Configuration Independent Binaries:

    OTHER BINARIES TO BUILD: YES
    (C) <sys>/obj/cserrc.o
    (C) <sys>/stdlib/libCTAL.so
    (C) <sys>/stdload/CTAL.so
    
    COMMENTS:
    When calling the C serrc_op_ext function with more then 9
    serrc_list items the C stack gets overwritten causing an
    incorrect dump number to appear on the console. The C library
    function cserrc.asm is incorrectly setting up the pointer to
    the stack when processing the serrc list items. As a result of
    this, eventually the stack gets overwritten.
    

Problem conclusion

  • SOLUTION:
    CSERRC.asm was changed to use ICST_WRK instead of ICST_LEN to
    allow proper room in the stack.
    The setting up the scon for the serrc list items was changed to
    use a STH instrcution instead of the STC so that more then 31
    serrc_list items can be handled.
    
    COREQS: NO
    None.
    
    MIGRATION CONSIDERATIONS: NO
    None.
