[open-cobol-list] Bug in GnuCOBOL 1.1: reporting undefined paragraph

[Scott McKellar]

When I PERFORM an undefined paragraph (probably because I mistyped the 
paragraph name, GnuCOBOL 1.1 reports my blunder, naturally.  However it 
attributes the error to the last paragraph in the program, not to the paragraph 
where the error actually occurs.

Consider the following minimal example:

       IDENTIFICATION DIVISION.
       PROGRAM-ID.  badperform.

       PROCEDURE DIVISION.

       0000-mainline.
           perform 1000-begin-job.
           perform 2000-do-stuff.   *> misspelled
           perform 3000-shut-down.
           STOP RUN.

       1000-begin-job.
           display 'I am starting up'.

       2000-do-some-stuff.
           display 'I am doing stuff'.

       3000-shut-down.
           display 'I am shutting down now'.



>cobc -x -Wall badperform.cob
badperform.cob: In paragraph '3000-shut-down':
badperform.cob:8: Error: '2000-do-stuff' undefined


The error should have been attributed to 0000-mainline, not to 3000-shut-down.  
If GnuCOBOL can't keep track of where the error occurs, it shouldn't attribute 
it to any particular location; that's just needlessly misleading.


Environment: Red Hat 4.1.2.  I have not tried GnuCOBOL 2.0; maybe it behaves 
better in this regard.
