Q108284: FIX: DX2010 w/ GETARG When RUNQQ Takes Five or more Arguments

Article: Q108284
Product(s): Microsoft Fortran Compiler
Version(s): 1.0
Operating System(s): 
Keyword(s): 
Last Modified: 24-MAR-2000

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft FORTRAN PowerStation for MS-DOS, version 1.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Using RUNQQ to spawn an application that uses five or more command-line
arguments causes the spawned application to produce the following error when the
spawned application uses GETARG:

  DOSXMSF : error DX2010: invalid pointer passed to free or realloc

RESOLUTION
==========

Use SYSTEMQQ instead of RUNQQ to spawn programs using five or more command- line
arguments.

STATUS
======

Microsoft has confirmed this to be a problem in FORTRAN PowerStation version 1.0
for MS-DOS. This problem has been resolved with FORTRAN PowerStation maintenance
release version 1.0a for MS-DOS.

FORTRAN PowerStation version 1.0 can be differentiated from the maintenance
release version 1.0a by invoking the linker. Typing "link32 | more" from
\F32\BIN directory will show version 2.8 for FORTRAN PowerStation version 1.0,
and it will show version 1.0f for the maintenance release version 1.0a.

MORE INFORMATION
================

The sample programs that reproduce this problem are shown below (no compile
options for either program):

Sample Code #1 (Main Spawning Program)
--------------------------------------

   include 'flib.fi'
        include 'flib.fd'
        integer*4 result
        result=RUNQQ('test.exe','-a -b -c -d -e')
        write(*,*) 'result = ',result
        end

Sample Code #2 (TEST.EXE)
-------------------------

        character*40 buffer
        integer*2 j,status
        k=nargs()
        write(*,*) 'k = ',k
        do j=0,k-1
           call GETARG(j,buffer,status)
           write(*,*) buffer,status
        enddo
        end
