Here's a cleaned up example that reproduces the bug (when endl is replaces by
"\n"). It seems the filter is a red herring.

#include <iostream>
#include <sstream>
#include <boost/iostreams/filtering_stream.hpp>

int main()
{
    boost::iostreams::filtering_ostream out;
    std::ostringstream os;
    out.push(os);
    out << "test" << std::endl;
    //out << "test" << "\n";
    std::cout << os.str();
}
