[Boost-users] Boost::tokenizer and reverse iterators

I'm using boost v1_31_0 and gcc v3.3.2

In experimenting with boost::tokenizer to meet a requirement that I 
have, I've tried hooking it to a reverse iterator.
This act produced a run-time error.

This is the code:
  const string test = "One:Two:Three:Four";
  typedef char_separator<char> Sep;
  typedef tokenizer<Sep,string::const_reverse_iterator> Tok;
  Sep sep(":");
  Tok t(test,sep);
  for (Tok::iterator iter=t.end();iter!=t.begin();++iter)
    cout << *iter << endl;

Executing this produces continous output of "garbage".

Switching the ".end()" and ".begin()" references in the for loop doesn't 
fix this problem.
Switching from "const_reverse_iterator" to "const_iterator" produces the 
following output:
  One
  Two
  Three
  Four

Is there a way to use a reverse iterator with boost:tokenizer?
