If I store it in the iterator I get crashes because a reference is
floating around to the long dead temporary iterator returned from post
increment. I can store it in the parent (container) class of the
iterator ( what I do now anyway ) but I need to store two values with
post increment.

If only so nobody else will have to go through what I just did today
and yesterday I will make the patch. I'll post to the C++-sig when
I've got it.
