 Not sure whether it's related, but there's a comment in edebug.el:

;; edebug-all-defs and edebug-all-forms need to be autoloaded
;; because the byte compiler binds them; as a result, if edebug
;; is first loaded for a require in a compilation, they will be left unbound.

But despite this explanation these two variables aren't autoloaded.
