13075	gzip_decompressor cannot be pushed to filtering_stream if provided with input_seekable	hellohee	Jonathan Turkanis	"There is a ticket regarding making filtering stream seekable: [https://svn.boost.org/trac/boost/ticket/2449]
However, the solution doesn't apply to situations where gzip decompressor is pushed.

boost::iostreams::filtering_stream<boost::iostreams::input_seekable> instream;
boost::iostreams::file_source file(filename, std::ios_base::in | std::ios_base::binary);
instream.push(boost::iostreams::gzip_decompressor());   // -> fails HERE
instream.push(file);"	Bugs	new	To Be Determined	iostreams	Boost 1.63.0	Problem		gzip, seekable
