Article Last Modified on 3/24/2000



The information in this article applies to:

  • Microsoft FORTRAN PowerStation for MS-DOS 1.0



This article was previously published under Q108284

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
