Hi folks.
I'm not a Boost.ICL expert, but we detected this one failure with our in-development STL and this test case:
template
void interval_set_element_iter_4_discrete_types()
{
typedef IntervalSet<T> IntervalSetT;
typedef typename IntervalSetT::interval_type IntervalT;
typedef std::vector<T> VectorT;
IntervalSetT set_a;
set_a.add(I_I(1,3)).add(I_I(6,7));
VectorT vec(5), cev(5);
vec[0]=MK_v(1);vec[1]=MK_v(2);vec[2]=MK_v(3);vec[3]=MK_v(6);vec[4]=MK_v(7);
cev[0]=MK_v(7);cev[1]=MK_v(6);cev[2]=MK_v(3);cev[3]=MK_v(2);cev[4]=MK_v(1);
VectorT dest;
std::copy(elements_begin(set_a), elements_end(set_a), std::back_inserter(dest));
BOOST_CHECK_EQUAL( vec == dest, true );
dest.clear();
std::copy(elements_rbegin(set_a), elements_rend(set_a), std::back_inserter(dest));
BOOST_CHECK_EQUAL( cev == dest, true );
dest.clear();
std::reverse_copy(elements_begin(set_a), elements_end(set_a), std::back_inserter(dest));
BOOST_CHECK_EQUAL( cev == dest, true );
dest.clear();
std::reverse_copy(elements_rbegin(set_a), elements_rend(set_a), std::back_inserter(dest));
BOOST_CHECK_EQUAL( vec == dest, true );
}
which produces this failure:

We are considering reverting this enforcement of iterator category tag in our STL, but technically a standard library appears within its rights to reject this.
