12873	boost.heap calls non-existing constructor of iterator_adaptor	Bart van Merrienboer <bart.vanmerrienboer@…>	timblechmann	"boost.heap tries to call the constructor `boost::iterator_adaptor(0)`, which doesn't exist, in several places. For example in `boost/heap/detail/mutable_heap.hpp` (lines 225-243):

{{{
        typedef boost::iterator_adaptor<ordered_iterator,
                                        const_list_iterator,
                                        value_type const,
                                        boost::forward_traversal_tag
                                      > adaptor_type;

        typedef const_list_iterator iterator;
        typedef typename q_type::ordered_iterator_dispatcher ordered_iterator_dispatcher;

        friend class boost::iterator_core_access;

    public:
        ordered_iterator(void):
            adaptor_type(0), unvisited_nodes(indirect_cmp()), q_(NULL)
        {}

        ordered_iterator(const priority_queue_mutable_wrapper * q, indirect_cmp const & cmp):
            adaptor_type(0), unvisited_nodes(cmp), q_(q)
        {}
}}}

This will result in ""no matching constructor"" compilation errors when trying to construct e.g. an `ordered_iterator` for a `d_ary_heap` (see attached program).

The same non-existing call is made on `detail/mutable_heap.hpp:193`, `detail/stable_heap.hpp:534`, and `detail/tree_iterator.hpp:214,218,231,340`"	Bugs	reopened	To Be Determined	heap	Boost 1.63.0	Problem
