id summary reporter owner description type status milestone component version severity resolution keywords cc 10072 filtering_stream::size() is not const Georg Baum Jonathan Turkanis According to the documentation at http://www.boost.org/doc/libs/1_55_0/libs/iostreams/doc/classes/filtering_stream.html, filtering_stream::size() should be const, but it is declared non-const. The implementation does not change the class (it calls the const metzhod chain_->size()). Therefore I believe that the non-constness is an oversight. Please make size() const to match the documentation. Bugs new To Be Determined iostreams Boost 1.55.0 Problem
