I tried calling out.reset() to the filtering_ostream object.  This has 
the desired effect, as the data is written to file before "out" falls 
out of scope, but then when the end of the scope is reached, my program 
crashes in the destructor.

If this is not the right way to flush the stream, what should I be doing 
instead?  I tried strict_sync() but this returned false because it looks 
as though the compressor is not flushable (although I could not find 
anything about this in the documentation).

I am working in Visual Studio .NET 7.1.
