Hi, All!

Anybody knows, does we really need to call std::basic_streambuf::sync in 
boost::archive::basic_binary_iprimitive destructor?
Is it possible to not call it?

I ask it because the call of sync with file stream buffer leads to 
skipping of the unreaded input data.
I think it is not good, or al least it must be clear described in 
documentation, that binary_iarchive when used with file stream skips to 
the end of a stream.
