Subject: 25.0.50; Edebug eval expression broken

From: [email-masked]
Date: Thu, 15 Jan 2015 14:19:57 -0600

When using edebug to debug an elisp function, 'e'
(edebug-eval-expression) does not eval the expression in the execution
environment.

First, create a file "~/debug-edebug.el" containing:

(defun sal-debug ()
  (interactive)
  (with-current-buffer (get-buffer-create "sal buffer")
    (message "current-buffer: %s" (current-buffer))))

Then, starting from emacs -Q:

(find-file "~/debug-edebug.el")

;; place cursor in function body
C-u C-M-x
M-x sal-debug

;; step until inside the "with-current-buffer"

e (current-buffer)

-> <buffer #debug-edebug.el> WRONG! should be <buffer sal buffer>
