APAR status
Closed as program error.

Error description
Security calls are being made from the WebSphere code, using SAF
call 'FASTAUTH' passing in the ENVRIN= parameter.  The pointer
used in the ENVRIN= parameter was sometimes incorrect, which
was causing Top Secret code to ABEND.
Top Secret has provided code to prevent the abend.  This apar
is to correct the WebSphere call, such that is passes valid data
on the ENVRIN= parameter during the FASTAUTH call.
.
Top Secret Fixes are listed in Informational APAR, 
II13427,
which WebSphere keeps as current as possible with security OEM
issues that affect WebSphere customers.

The ENVR body is not required by SAF to be in contiguous
storage with the ENVR header, but WebSphere stores the entire
ENVR contiguously. When the ENVR header/body pair is copied,
The pointer from the ENVR header that connects it to the ENVR
body is not being updated to point to the new copied ENVR body.
At some point in time, the source ENVR goes away and the
pointer is targetting freed storage, yielding the 0C4 abend.
Problem conclusion
Updated the copied ENVR header to point properly to the ENVR
body after the storage copy.
