APAR status

• Closed as program error.

Error description

• A test case using the CSHIFT function, compiled with the xlf2003
  compiler invocation, is encountering a signal 11 fatal error in
  the xlfhot component of the compiler.
  
  
     ====  TEST CASE  ====
  
     SUBROUTINE testsub()
      IMPLICIT NONE
      INTEGER :: num, size
      INTEGER, ALLOCATABLE, DIMENSION(:) :: ar
      num=2
      ALLOCATE(ar(num))
      ar = CSHIFT(ar,shift=-1)+size
     END SUBROUTINE testsub
  
  
  
  > xlf2003 -c test.f90
  ** testsub   === End of Compilation 1 ===
  1501-224 (S) fatal error in /opt/ibmcmp/xlf/bg/14.1/exe/xlfhot:
    signal 11 received
  >
  

Local fix

• Compile with a non-xlf2003 invocation, i.e. xlf or xlf95
  

Problem summary

• PROBLEM DESCRIPTION:
  Signal 11 error from xlfhot with xlf2003 when CSHIFT/EOSHIFT is
  used in an expression.
  
  USERS AFFECTED:
  Users who call CSHIFT/EOSHIFT in another expression.
  

Problem conclusion

• The compiler now creates the necessary temporary for the result
  of CSHIFT/EOSHIFT before using it in another expression.
  

Temporary fix
