11558	boost transform iterator doesn't work with libc++	rnickb731@…	jeffrey.hellrung	"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);
