Edebug fails to instrument code which uses cl-defstruct. I found an example of
the problem in Emacs’s source tree. Here are the steps to reproduce it:
1. emacs -Q
2. C-x C-f emacs/lisp/emacs-lisp/avl-tree.el RET
3. M-x toggle-debug-on-error RET
4. M-x edebug-all-defs RET
5. M-x eval-buffer RET
Result: invalid-read-syntax error. See attachment for backtrace. The cursor is
at :named in the code excerpt below:
(cl-defstruct (avl-tree-
;; A tagged list is the pre-defstruct representation.
;; (:type list)
:named
(:constructor nil)
(:constructor avl-tree--create (cmpfun))
(:predicate avl-tree-p)
(:copier nil))
(dummyroot (avl-tree--node-create nil nil nil 0))
cmpfun)
