BUG: GPF on Expanding Adjustable Size Array After Execution

Last reviewed: July 13, 1995
Article ID: Q106641

The information in this article applies to:

Microsoft FORTRAN PowerStation for MS-DOS, versions 1.0 and 1.0a

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:

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

Set a breakpoint at:
```
      print*, arr(1)
```
"Go" (press F5).
Type ARR in the Watch window, and expand it.
Shrink it back to "+ARR = {...}" and press F5 again.
After the program finishes execution, again expanding the variable ARR may cause a GP fault.
