#933 Compiler Segmentation Fault on bad expressions

[Denis HUGONNARD-ROCHE]

Hi Simon
When i compile the following program , it produces a segmentation fault.

       IDENTIFICATION DIVISION.
       PROGRAM-ID. toto.
      *
       DATA DIVISION.
      *
       WORKING-STORAGE SECTION.
      *-----------------------*
      *
      *
       PROCEDURE DIVISION.
      *------------------*
      *
       A00-MAINLINE.
      *------------*
      *>
           IF +
           THEN
                   display 'ok' .
      *>
           GOBACK.
      *>
~                                                                                                                       

I think that the problem is on* expr_token_no_is* bison rule . It occurs for other sub rules :
+ , ) , ) ...
I think most of the sub rules are not useful except AND and NOT

This error is finally fixed with [r5247]. Please check again if you think we should adjust the rules (may<be give that a test and see what the test cases say).

After your feedback and a possible adjustment to the rules, we can then close this issue.

Hi Simon
Yes . This case is solved.
But while testing i found another case that produce a core dumped.
Here it is :

       IDENTIFICATION DIVISION.
       PROGRAM-ID. test.
      *
       DATA DIVISION.
      *
       WORKING-STORAGE SECTION.
      *-----------------------*
      *
      *
       PROCEDURE DIVISION.
      *------------------*
      *
       A00-MAINLINE.
      *------------*
      *>
           IF NOT (+)
           THEN
                   display 'ok' .
      *>
           GOBACK.
      *>

i'll try to find other cases and give you an update
PS : did you have time to have a look at the last version of 'cob_decimalèpow' and the cordic ln program test ?
