The error reported is: Wrong type argument: listp, # edebug--display-1: Wrong type argument: listp, # This is a regression as it works in Emacs-26, but fails in Emacs-27. Reproduction: In clean emacs -q M-x hanoi jump to hanoi function C-u C-M-x M-x hanoi After stepping through into hanoi with point still in C-M-x and step once more. I use this workflow quite a lot when debugging. I may start to debug a function, decided I have seen enough, to un-instrument so I don't see it debugged again.
