APAR status

• Closed as program error.

Error description

• An abend0C4 may occur in DFHUEH at offset x'1008' because
  register 13 is not pointing to the CSA.  This can happen when
  control returns back to DFHUEH after a global user exit program
  has executed.  DFHUEH is not re-establishing the proper
  environment by ensuring that register 13 is pointing to the CSA.
  This is occurring within a very narrow code path through
  DFHUEH.

  In the reported problem, an 0C4 abend occurred in module DFHUEH
  on return from an EXIT.  DFHUEH was attempting to reference
  field sma_isolation_flags but a base register used to address
  the dsect containing this field was incorrectly set up and
  caused an 0C4.  This also presented as a DFHAP0002 error.
