BACKSPACE crossing 4gb boundary results in Error 23

[Deleted_U_Intel]

We're running:

Compaq Visual Fortran Optimizing Compiler Version 6.6 (Update C)
Compaq Visual Fortran 6.6-4088-47D3B

We have formatted sequential files >4gb that we need to read in reverse using the BACKSPACE command. If the BACKSPACE command is executed when the record to be backspaced spans the 4gb boundary of the file, we get ERROR 23, BACKSPACE ERROR. BACKSPACE seems to work OK when the records are fully contained below 4gb or fully contained above 4gb. Reading forward across the 4gb boundary also works OK. Also seems to work OK for binary sequential records crossing 4gb.

Is there a patch or fix to allow BACKSPACE to work correctly with formatted sequential files when the record spans the 4gb boundary?

There are and will be no more updates to CVF. I'll try this out in Intel Visual Fortran to see if it works - if it doesn't, we'll fix it.

I can confirm that this is broken in CVF 6.6 but that it works in Intel Visual Fortran 8.1.025.
