CAUSE
The APPC application was deallocating the verb control block (VCB) that it
had passed to the [MC_]RECEIVE_AND_POST function prior to calling TP_ENDED.
This caused an error when the APPC interface attempted to set the event
handle indicating final completion of the [MC_]RECEIVE_AND_POST VCB.
RESOLUTION
The APPC application should maintain the state of the RECEIVE_AND_POST VCB
until the function has fully completed.
