Yes, they're only guaranteed to work within a particular Emacs session.
In practice they're fairly stable across sessions, but they depend for
example on the size of fixnums, so they're different in a 32bit build of
Emacs and a 64bit build of Emacs. And we don't guarantee that they
don't change from one version to another.
