Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Sometimes CICS can pass low core instead of registers at the
  time of the interrupt (commregs) to LE during
  rununit_end_invocation.

  ****************************************************************
  64-bit registers are not available when, for example, an
  interrupt occurs when the CICS RB was not in control during a
  loop. At rununit_end_invocation, CICS should pass LE the 31-bit
  registers in place of the 64-bit registers, but instead passes
  storage held at low core. A consequence of this is that LE
  doesn't produce its diagnostic information in CEEMSG.
  

Problem conclusion

• DFHAPLI1 has been changed to provide LE with the 31-bit
  registers when the 64-bit registers are not available.
