Re: [Boost-users] [serialization] different behaviourbetweenxml_wiarchive and binary_wiarchive

Thanks for your answer Robert,

Some of the files that did not work with binary_wiarchive are working now
with binary_i/oarchive.
Unfortunately some still don't.
I'm trying to figure out what the reason for the trouble might be. The 
exception_code changed 'unregistered_class' to 'stream_error', because in
some
occasions the istream fails.

Regards

Oliver
