The original report is below.

Currently, counting_iterator<T>::reference is Incrementable const&. This makes reverse_iterator< counting_iterator<T> >::dereference return a reference to a temporary variable:

The problem is that iterator::reference is expected to stay valid even if the iterator it was obtained from is dead.",Bugs,new,Boost 1.38.0,iterator,Boost 1.37.0,Problem,,counting_iterator reverse_iterator,flast@…
