10450	Undefined behavior in boost::filesystem::detail::directory_iterator_construct	egrindha@…	Beman Dawes	"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); }
}}}
