#11558: boost transform iterator doesn't work with libc++

 Reporter:  rnickb731@…  |       Type:  Bugs
   Status:  new          |  Milestone:  To Be Determined
Component:  None         |    Version:  Boost 1.57.0
 Severity:  Problem      |   Keywords:
-------------------------+------------------------------
 The following code won't compile with clang using these options:

 clang++ -std=c++14 -stdlib=libc++ main.cpp

 #include <boost/iterator/counting_iterator.hpp>
 #include <boost/iterator/transform_iterator.hpp>

 double f(int i) { return i; }

 int main() {
   auto i =
 boost::make_transform_iterator(boost::make_counting_iterator(3), f);
   std::next(i);
   return 0;
 }

 It gives me this error:

 main.cpp:8:3: error: no matching function for call to 'next'
   std::next(i);
   ^~~~~~~~~
