Re: [boost] Re: Boost::Python iterators are off by 1?

Yes, it was a bit of a simplification on the real iterator that was
causing the problem, but I forgot that I hadn't implement post
increment correctly. At the time I didn't see how it would get me into
trouble, now I do :) My input iterator is a little tricky to create
because I don't know how many times it can be incremented before
reaching the end. The end() iterator simply holds a NULL pointer,
incrementing it does nothing. When the begin() iterator is incremented
enough I set it's pointer to NULL and it becomes equal to end(). This
causes a lot of non-standard issues ( like end() == end()+1 ). I'm
hoping that particular one doesn't cause a problem for me.

Again it seems the trouble is with me rather than Boost::Python.
Thanks for setting me straight, you saved me a lot of debugging time.
