APAR status

  • Closed as program error.

Error description

  • Change Team finds ABEND0C4 occurs in CSQBPAPI as it attempts to
    restore the state of the registers prior to returning to its
    caller. At the time of register reinstatement, however, the
    savearea register has been changed already, causing MQ to try to
    access storage that is part of unallocated storage. Root cause
    is due to incorrect code that was generated to restore register
    values at the end of CSQBPAPI.
