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.
