I agree with Hervé, I wouldn't have thought to use numeric::interval for your use case because I wouldn't expect you are using enough of what that library provides to justify the dependency.  std::pair<void *> and a predicate contains(pair1, pair2) would be fine.  You could even store your std::pair<void *> in a std::set and look up which block a given std::pair<void *> was contained in quite conveniently using std::set::lower_bound and the less than operator of std::pair as the comparator on std::set.  Similarly, I wouldn't suggest that you use my gtl interval concept with a gtl::interval_data<void *> either because I don't think the benefit you might get out weighs the cost of a dependency.
