Comment (by Charles Olivi <charles.olivi@…>):

 Hi,

 There is no defect, the std::distance calls iteratively the same operation
 on the single_pass_traversal_tag iterator, i.e. increment().

 recursive_directory_iterator is shared_ptr implemented and increment()
 call pops one element from the iterator stack.

 In the end, when you enter your loop, iter points to end() which makes the
 segfault you get.
