Obtain the fix for this APAR



APAR status
Closed as program error.

Error description
After running an application the BBODMN creates a SVC dump and a
CEEDUMP.  The CEEDUMP has a TRACEBACK for signal=SIGSEGV and
sicode=SEGV_PROTECT.  In the actual flow of method calls in the
TRACEBACK there was a call to Current::delete_RACO(MVS::RACO*)
immediately before the exception on call to BBOSSACX.  This RACO
function was invoked as a result of an earlier call to
ACR_ExecutionThread::RemoveAndProcessWork(ThreadCleanUp*).

The ABEND and/or CEEDUMP do not affect the running of the
application.

The ABEND and/or CEEDUMP resulted from an uninitialized pointer
to the local RACO being used during session cleanup. This
pointer contained an invalid address which lead to the ABEND
when it was used to release the storage.
Problem conclusion
Code has been changed in part bboclspc.plx to initialize the
local RACO pointer to zero during initialization, which was
causing a protection exception during session cleanup since it
contained an invalid address when used to release storage.
