Hi Jonathan, Thanks for helping me out!! I've tried your proposition below and it does the trick, even with actual encryption going on: out << "test" << std::endl; //this works //out << "test" << "\n"; //this does not One remark: he code above works on my vc71 debug setup (cl called through bjam v2 build v10), but if I read your earlier mail correctly it should be the other way around and hang as well? One question: is this behaviour intended? I will try some more stuff (with some other containers , the copy/adapt etc) and source/sink - apart from encryption I am in need of a audio source/sink. I'll let you know :) - It's great stuff! Cheers, Dirk (Sorry the code didn't compile, forgot to match the filter names).

I would love to use the boost::iostreams lib, so I created a filter (which, in this case, does encryption)

but instead of passing it std::cout I would like to pass it some other stream, a stringstream for instance (or any kind of ostream/istream, depending on the direction).

However, I was very surprised to find the following code taking 100% cpu and not returning. It probably means I did something wrong, but I can't seem to find it.

Here's a cleaned up example that reproduces the bug (when endl is replaces by "\n"). It seems the filter is a red herring. Jonathan #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(); } _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
