     Type:  Bugs                          |     Status:  new
Milestone:  To Be Determined              |  Component:  iterator
  Version:  Boost 1.57.0                  |   Severity:  Problem

------------------------------------------+------------------------------
 If one uses the `zip_iterator` class template with
 `std::vector::insert(It1, It2, It2)`, with `_GLIBCXX_DEBUG` defined, g++
 return a compilation error:
 {{{
 /usr/include/c++/4.9.2/debug/functions.h:220:69: error: invalid
 initialization of non-const reference of type ‘boost::tuples::cons<int&,

        return __foreign_iterator_aux4(__it, std::__addressof(*__other));
                                                                      ^

 }}}

 The attached test case `test.cpp` shows the error, with g++-4.9.
