Using default-constructed instances of the hash algorithm, instead of copies, makes the hashing seed-independent, which means that a way to engineer collisions will work regardless of the seed used.

Can’t you construct h2 by seeding it with a result from h (possibly after updating h with the range size)? Joaquin M Lopez Munoz
