LI77044: STABSTRING UNDEFINED TYPE ERROR

October 2012 Update for XL Fortran for Linux, V13.1

APAR status

• Closed as program error.

Error description

• Debug stabstrings generated with the -g compiler option are
  using a stab type that has not yet been defined.  This is
  causing the -bstabcmpct:2 linker option to encounter an error
  while interpreting the stabstrings:
  
  
  ld: 0711-393 STABSTRING ERROR: Symbol table entry 22, object
  file /home/test.o
  A stabstring refers to type 13, which is not defined.
  
  
  Using the 'dump -t test.o' utility shows:
  
  [22] m 0x00000000 -2 0 0x8c 0x0000 :t14=ar0;1;3;13
  
  , where the '13' is a type that has not yet been defined.  The
  missing type is related to declaring an array using a
  passed subroutine parameter, i.e.
  
  
        SUBROUTINE TEST1(VAR1,VAR2)
        INTEGER*2 VAR1,VAR2(3,VAR1)
  

Local fix

Problem summary

• PROBLEM DESCRIPTION:
  The linker stabstring compact feature encounters an issue with
  improper forward references for arrays with variable bound.
  
  USERS AFFECTED:
  Users of -g and -bstabcmpct:2
  

Problem conclusion

• The generation of stabstrings for variable bound arrays was
  corrected.
  

Temporary fix
