APAR status

• Closed as program error.

Error description

• When compiling the following test case with debug information
  enabled, the compiler is generating an invalid stabstring that
  uses a type that is not defined.
  
  When using the AIX linker's option -bstabcmpct:2, the following
  error is output:
  
  ld: 0711-393 STABSTRING ERROR: Symbol table entry 36, object
  file test.o
          A stabstring refers to type 7, which is not defined.
  
  The symbol can be checked with the 'dump -t test.o' command:
  
  [36] m 0x00000000 -2 0 0x8c 0x0000       :t29=*7
  
  There is no definition for a type '7', and therefore the error
  is output.
  
     =====  TEST CASE  =====
        REAL*8 FUNCTION FOO()
        IMPLICIT NONE
        REAL*8    FOO_ENTRY      ! Entry point.
        REAL*8    F1
        EXTERNAL  F1
  
        FOO=7
        ENTRY FOO_ENTRY(F1)
        RETURN
        END
  
        PROGRAM test
        VAL = FOO()
        WRITE (*,*) VAL
        STOP
        END
  
  
  Compile with:  xlf -g test.f -bstabcmpct:2
  

Local fix

• Compile with a lower stabstring compaction level
  

Problem summary

• PROBLEM DESCRIPTION:
  Debug information for alternative ENTRY points is not
  accounting for functions as parameters.
  
  USERS AFFECTED:
  Those compiling Fortran code with -g .
  

Problem conclusion

• The issue was corrected, and the correct stabstring is now
  output.
  

Temporary fix
