Hi Mikael, thanks, what is the use of BinaryPropagator::dispose if this class does not register itself (it does not use force nor unforce)?

The layered graph propagator, for example, has a reference to a DFA that is shared. If a propagator does not register for deletion, then the dispose-member will not be run when a space is deleted. Note that the members force(Space*) and unforce(Space*) will be replaced in Gecode 3.0.0 with the more general Space-members notice and ignore.
