I figured it out, utils::output_counter was not assignable,
so the compiler could not generate the operator= method for
function_output_iterator<output_counter>

Making output_counter copyable solved the problem.

thanks, I always seem to figure things out about 5 minutes after
posting to a list, even after 1 hour of struggling first.
