Issue: NoSuchElementException

[acurat]

Ran into this error trying to summarize a program. Please let me know if you need any other info.

could you paste the space-separated version of the line 01DFHCOMMAREAPICX(99999) here?

[acurat]

Pasting that part of the code...

       LINKAGE SECTION.

       01  DFHCOMMAREA              PIC X(99999).

       PROCEDURE DIVISION USING DFHCOMMAREA.

       0000-MAINLINE.

           STRING WS-THIS-PROGRAM
                   '0000-MAINLINE'
           DELIMITED BY SIZE INTO TDQMSG
           PERFORM 9988-CSMT-LOG

I'm unable to reproduce this issue from this code fragment. Could I ask you to do two things?

• I've added a debugging log for this specific issue in commit 97b7bd3f8900b608a19687fe42a6381f293db558. Could you run the program with this build, and paste the resulting log just before the exception?
• If possible, could you reduce the problematic program to its smallest possible size and post it here? This seems to be specifically an issue with processing the record sections, so I think you can omit everything in the PROCEDURE DIVISION, and reduce the size of the data sections to the minimum size where you still see the problem.
