Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

It's not a heavy bug, but it's simple to ilustrate and maybe indicates
some other instabilities.

1. Open a new temporary buffer with C-x b tmp
2. Set it to emacs-lisp-mode with M-x emacs-lisp-mode
3. Exactly from the left side enter the following lines

(let (x)
  (pushnew 'a x))

(let (x)
  (push 'a x))

4. Now press the key combination C-u M-C-x anywhere inside the first
   let that spans the first two lines. It protests with
   "edebug-match-symbol: edebug-keywordp is not a form-spec or
   function "

5. If you try the same function inside the second let, it works
   fine. It instruments the code and steps to firs line.
