Article ID: 106641

APPLIES TO

• Microsoft FORTRAN PowerStation 1.0 Standard Edition
• Microsoft Fortran PowerStation 1.0a for MS-DOS

---

This article was previously published under Q106641

SYMPTOMS

After the program finishes execution under the debugger, expanding an adjustable size array in the Watch window may cause a general protection (GP) fault.

STATUS

Microsoft has confirmed this to be a problem in FORTRAN PowerStation version 1.0 for MS-DOS.

This is not a problem in FORTRAN PowerStation 32.

MORE INFORMATION

To duplicate the problem:

1. Build the following sample code in debug mode from the Visual Workbench:

         real*4 arr(20)
         arr = 7.
         Call Sub (arr, 20)
         End
   
         Subroutine Sub (arr,n)
         real*4      arr(n)
         arr(1) = n+1.2
         print*, arr(1)
         Return
         End
                           

2. Set a breakpoint at:

         print*, arr(1)
                           

3. "Go" (press F5).
4. Type ARR in the Watch window, and expand it.
5. Shrink it back to +ARR = {...} and press F5 again.
6. After the program finishes execution, again expanding the variable ARR may cause a GP fault.
