Comment (by gonzalobg88@…):

 But does it say that user-defined signed integer types are not allowed?

 This is just debug code (inside a BOOST_ASSERT), and IMO the problem here
 is relying on implicit conversions.

 Why is this debug code comparing a difference_type which is typically
 std::ptrdiff_t with an int? Doesn't it make sense to construct a
 difference_type since it is going to be compared with one anyways?
