Error description
SIGSEGV (ABEND0C4) at offset 08C6 in
ORB_Request::read_asynch_message(ORB_Request::ORBR_ReturnArea&,
AsynchData*,SessionHandle*,G
suddenly.
the ABEND0C4 occured because the callers R3+0 is null.
The SessionHandle passed to read_asynch_message() has a pointer
to the Session at offset +0, and in this case the value of the
pointer is 0x00000000. It should not be zeros.

****************************************************************
The Session address contained in the SessionHandle passed to
read_asynch_message was 0.  The storage for this SessionHandle
is contained within the AsyncData area within the Session
Object storage.  Cleanup code from a prior use of this Session
object had cleared the Session pointer component of the
Session objects' SessionHandle after it was made available for
reuse.  Before this clearing occurred the Session Object was
allocated and initialized to a new connection.  The later
clearing of the Session pointer within the SessionHandle
corrupted the Session and caused the ABEND0C4.
Problem conclusion
Code has been modified to eliminate the clearing of the
Session pointer within the SessionHandle after the Session has
been made available for reuse.
