#4539: multi_array patch for VisualStudio 2010
 Reporter: Serg Repalov <repalov@…> | Owner: garcia
     Type: Bugs | Status: new
Milestone: Boost 1.44.0 | Component: multi_array
  Version: Boost 1.44.0 | Severity: Problem
 Keywords: multi_array, 2010 |
 The problem is incorrect iterator_category for multi_array::iterator.

 Due to use proxy class as reference int iterator, the type of
 iterator_category (selected in iterator_facade_types ->
 facade_iterator_category (iterator_facade_default_category)) is
 incorrectly (due to is_reference<Reference> is fail) assigned to
 std::input_iterator_tag. So the std::copy from MSVC 2010 is doesn't
 compile in Debug mode due to fail of additional checks.

 The problem also is described here:

 And also discussed here:

 The solution from last discussion is to use
 std::random_access_iterator_tag instead of
 boost::random_access_traversal_tag at array_iterator definition (in file
 boost\multi_array\iterator.hpp is not correct for const_iterator.

 I try to make more generic solution and create patch from it.
