Subject: [Boost-users] [ICL] lower(interval_set) doesn't compile
From: John Reid (j.reid_at_[hidden])

I'm not sure if I'm getting the wrong end of the stick from the docs or
perhaps I should raise this sort of thing as a bug report?
#include <boost/icl/interval_set.hpp>
namespace icl = ::boost::icl;
void interval_set_intersects() {
icl::lower( icl::interval_set< int >() );
}
gives:
