With the shortened version, you don't get to step into anything. As soon as the instrumented advice triggers, blam! > Which lines did you select? =C2=A0I think this is important, because > when a form is evaluated, Edebug displays in the echo area a message > showing the result of the evaluation, and if the result is a number, > it tries to display it as a character. =C2=A0So the end of the region you > select determines what character will Edebug try to display. A few lines at the start of the file, usually about ten or twenty. AFAICS, the start of etc/NEWS does not contain any composable character, just straight ASCII. > I don't see this message, perhaps because I used a different region.

I got a reproducible recipe with -Q emacs -Q M-: (setq force-load-messages t) C-x C-f bug.el ;; the file containing just the defadvice C-u C-M-x C-h n ;; select line 22 C-x n n Juanma
