APAR status

• Closed as program error.

Error description

• When compiling the following test case with debug information
  enabled, the compiler is generating invalid stabstrings for the
  ENTRY statement, func2.
  
  When using the AIX linker's option -bstabcmpct:2, the following
  error is output:
  
  ld: 0711-393 STABSTRING ERROR: Symbol table entry 30, object
  file test.o
          A stabstring refers to type 6, which is not defined.
  
  Looking at the object file shows the following stabstrings for
  func2:
  
    .stabx  ":t27=*6",0x00,0x8c,0x0
    .stabx  "func2:V27",0x00,0x85,0x0
  
  There is no definition for a type '6', and therefore an error is
  thrown.
  
  
     =====  TEST CASE  =====
        CHARACTER*20 FUNCTION func1 ()
  
         CHARACTER*20 func2
         ENTRY func2 ()
  
         func1 = 'a'
         func2 = 'b'
  
        RETURN
        END
  
        PROGRAM MAIN
         REAL*4 RET2
         RET2 = func1()
        END
  
  
  Compile with:  xlf -g -bstabcmpct:2 -bloadmap:output test.f
  

Local fix

• - Compile with a lower stabstring compaction level,
  -bstabcmpct:1
  

Problem summary

• PROBLEM DESCRIPTION:
  Missing stabstring type definition.
  
  USERS AFFECTED:
  Users with functions that contain ENTRY statements, compile
  with stabstring debug information, and use the -bstabcmpct:2
  linker feature.
  

Problem conclusion

• The stabstring generation was corrected.
  

Temporary fix
