In CPS the state of the program is captured in the continuation, which is a closure, which is allocated on the heap, and in any ancillary data structures pointed to by it. However, there's generally only a very small number of such closures -- typically only one -- and they are generally one-time use only. That means they can be freed as soon as they tail-call out.
