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.
