Subject: bug#10687: 24.0.92; Interactive edebug/eieio interaction
Date: Wed, 01 Feb 2012 15:00:05 +0100

Put the following in *scratch*, and say `C-u M-C-x' to edebug-instrument
it.

(defun test-edebug ()
  (interactive)
  (auth-source-search :max 1
		      :host "news.gmane.org"
		      :port '("119" "nntp")))

Then say `(test-edebug)' and step through the form.  Everything will be
fine.

But then say `M-x test-edebug'.  I get the following error when stepping
over the search function:

Wrong type argument: arrayp, auth-source-backend

I think the problem is that the function returns something defined as a
class by ieieio, but I have no idea why it being called interactively
should trigger the bug, and not otherwise.
