This is the same problem discussed in your other thread 'Another 
desperate ...'. It can be solved the same way, using reset() or pop().

I guess this would be a good place to ask: As a newcomer to the 
iostreams library, would you be surprised if

        copy(in, out)

where in and out are filter chains, automatically popped both chains, 
assuming this behavior was clearly documented?
