Comment (by anonymous):

 Just reproduced it with boost 1.58 after migration from 1.55.
 I tried to play with it and found how to make it work.

 Using const std::string instead of std::string, seems fix the problem

 {{{
 typedef boost::any_range<
     std::string,
     boost::forward_traversal_tag,
     const std::string,
     std::ptrdiff_t
 > range_t;
 }}}

 I haven't digged into any_iterator sources but seems it behave differently
 when Reference is const
