BUG: GPF on Expanding Adjustable Size Array After Execution

Article ID: 106641

Article Last Modified on 10/2/2003

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:

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.
