Testcover doesn't work on lisp/isearch.el in the Emacs source tree. It
fails on the first use of isearch-define-mode-toggle. I've created a
much simpler example which produces the same error message:

(defmacro my-defun (name &rest body)
  (declare (debug (symbolp def-body)))
  `(defun ,name () ,@body))

(my-defun foo (+ 1 2))

To reproduce the bug:
1. Save the above code as bug.el
2. emacs -Q
3. C-x C-f bug.el RET
4. M-: (require 'testcover) RET
5. M-x testcover-start RET bug.el RET

Result: "Wrong type argument: consp, nil" and foo does not get defined.
(symbol-function #'my-defun) reveals that there is a call to
edebug-after in the definition that did not get replaced by testcover-after.
