| Well, I'm a newbee with octave, so I guess I cannot contribute much here. It looks like binary save works, so I'll use that for the time being. It may also be a cygwin specific bug.

I see the problem, but I don't know of a quick fix.

When you installed Cygwin, did you choose to mount the filesystems in
text mode?  If so, then I think you can mount the filesystems in
binary mode to avoid the bug.
