Do you have any idea to fix this problem??
Yeah :( It appears that the old input iterator requirements require that *r++ returns value_type instead of a proxy. However, *r++ must be a proxy if the iterator is writable. Since there's no way to detect iterator writability reliably, I'm going to have to make *r++ return value_type whenever the specified iterator category is strictly std::input_iterator_tag. I'll let everyone know when it's checked in. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
