Thanks for the report. I'll look into this. I'm currently redoing it quite a bit, possibly to use function template overloading (like Daryle Walker suggests in this posting (http://aspn.activestate.com/ASPN/Mail/Message/1143265)), rather than the current class template specialisation of a helper class, and I've been discussing with Kevlin how to do it. That could make it easier to user-extend it, as you might then overload the lexical_cast template (and possibly call an existing function to do the conversion). Nevertheless, that shouldn't affect this case. The tests are also being redone to use the Boost unit test framework. Although I must admit that the above printout is quite informative, as well. :) However, using Boost.Test means I can replace the rather ad-hoc tests there.
