VM66336: PIPES WITH SPEC STAGE MAY RESULT IN ASSERT FAILURE 182 IN LOADSPAC IN FPLSPS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The SPEC stage in a pipeline may occasionally result in an
  assert failure 182 due to uninitialized memory.
  
  The assert failure produces a series of messages starting
  with
  
  FPLINX409E Assert failure 00000182 at xxxxxxxx
  FPLINX411I ... In LOADSPAC; offset 00001040 in FPLSPS 06/22/18
  11.40
  
  After the dumped register content, a FPLMSG001I is issued
  pointing to a SPEC stage.

  ****************************************************************
  The SPEC stage failed to initialize a local work area used to
  hold an intermediate expression result. After processing the
  item from the specification list, the cleanup code inspected the
  uninitialized location. This could incorrectly invoke the string
  cleanup routine that would fail on the integrity check.
  Even very simple use of the SPEC stage could be impacted.
  

Problem conclusion

• CMS Pipelines has been changed to ensure the local work area is
  initialized for each specification list item.
  
  During development, another defect in the module was corrected
  that could cause an Assert Failure A5 in routine BUFFERSE in
  module FPLFRE for a SPEC stage with multiple streams.
