Milestone:  To Be Determined                                         |   Component:  foreach     
  Version:  Boost 1.46.0                                             |    Severity:  Problem     
 Keywords:  BOOST_REVERSE_FOREACH, counting_iterator                 |  
---------------------------------------------------------------------+------
 The following code:

 {{{
 #include <iostream>
 #include "boost/foreach.hpp"
 #include <boost/iterator/counting_iterator.hpp>
 int main(int, char**) {
   boost::counting_iterator<int> start(0), end(10);
   std::pair<boost::counting_iterator<int>, boost::counting_iterator<int> >
 iterators(start, end);
   std::cout << "Counting: ";
   BOOST_REVERSE_FOREACH(int t, iterators) {
     std::cout <<t<<" ";
   }
   std::cout << std::endl;
 }

 }}}

 works fine with gcc-4.4.5 using -O3:

 {{{
 Counting: 9 8 7 6 5 4 3 2 1 0
 }}}

 but fails for gcc-4.5.0 and gcc-4.5.2 using -O3:

 {{{
 Counting: 70263556 70263556 70263556 70263556 70263556 70263556 70263556
 70263556 70263556 70263556
 }}}
