     Type:  Bugs                          |      Status:  new    
Milestone:  To Be Determined              |   Component:  GIL    
  Version:  Boost 1.51.0                  |    Severity:  Problem
 Keywords:                                |  
------------------------------------------+---------------------------------
 The following does not compile because it cannot be resolved whether a
 call to boost::range::fill_n or std::fill_n is correct


 #include <boost/array.hpp>
 #include <boost/gil/image_view.hpp>
 #include <boost/gil/image.hpp>
 #include <boost/gil/typedefs.hpp>

 #include <boost/range/algorithm/fill_n.hpp>

 namespace gil = boost::gil;

 int main( int argc, char** argv)
 {
     gil::image<boost::array<float,2> > img;

     std::fill( gil::view(img).begin(), gil::view(img).end(),
 boost::array<float,2>() );
 }
