This function my-fact works ok when I just call it.
However, when edebugged, it gets the error described below.

labels does have an edebug-form-spec property.

Would someone please DTRT, then ack?

               (fact-iter (1- n) (* n r)))))
    (fact-iter n 1)))

Now edebug `my-fact' (M-C-x) and call it with any argument. Edebug

I haven't checked whether this happens with other macros from cl.el,
too.
