[Bug-GnuCOBOL] Compiler crashes in empty perform when debugging mode was specified

[Harald Cordes | ITGAIN]

Hi,

 

I’m evaluating the usability of the GNU-COBOL-compiler for our purposes.

It looks good. I’ve found some issues we have to cope with,

e.g. where the compiler does not tolerate some minor flaws

and I’ve found a real bug. It’s a very minor one but I’d like to report it.

 

Adding a simple continue within the body of the inline-perform solves the problem.

 

The following program causes a crash of the GNU-COBOL-compiler:

 

 

       SOURCE-COMPUTER. IBM-390 WITH DEBUGGING MODE.

      

           PERFORM VARYING IND1 FROM 10 BY -1

                   UNTIL TST(IND1:1) NOT = SPACE

           END-PERFORM.

 

Message:

 

attempt to reference unallocated memory (signal SIGSEGV)

 

cobc: aborting compile of PERFFAIL.cbl at line 16

 

 

I’m using GNU-COBOL:
