The following works for me when I call it in a function using boost 
1.33.1 (in Windows XP):

        using namespace std;
        namespace io = boost::iostreams;

        std::ifstream ifs(infile, std::ios_base::in | std::ios::binary);
        io::filtering_ostream out;

        out.push(io::gzip_compressor());
        out.push( io::file_sink(outfile, ios_base::out | ios_base::binary));
        out << ifs.rdbuf();
        ifs.close();
        out.flush();
        out.reset();

// After the reset, the output file is closed.
