I definitely cannot reproduce the behavior you show on that page:
The code stops at "(message "Before: %d" foo)" because foo has
value nil at that point which is incompatible with the %d format.
If I get rid of this bug, then I bump into the next error which is that
`let' raises "Frame-local vars cannot be let-bound".
Note that frame-local variables have been deprecated since Emacs-22.2,
and I definitely intend to remove support for them (tho for Emacs-24.1,
the plan is currently only to remove support for let-binding them).
