#10450: Undefined behavior in
boost::filesystem::detail::directory_iterator_construct
------------------------------+------------------------
 Reporter:  egrindha@…        |      Owner:  bemandawes
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  filesystem
  Version:  Boost 1.56.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+------------------------
 boost/libs/filesystem/src/operations.cpp:2178:28: runtime error: reference
 binding to null pointer of type 'struct error_code'

 The problem is this line: it.increment(*ec);

 ec is 0 when directory_iterator_construct is called from
 operations.hpp:793
 {{{
 explicit directory_iterator(const path& p)
         : m_imp(new detail::dir_itr_imp)
           { detail::directory_iterator_construct(*this, p, 0); }
 }}}
