27.0.90; Evaluating a function while using edebug breaks |

Gnus/5.13 (Gnus v5.13) Emacs/27.0.90 (gnu/linux) |
Edebug fails while tracing a function, if that function is evaluated
during the edebug session. The error reported is:
Wrong type argument: listp, #<marker at 4045 in hanoi.el>
edebug--display-1: Wrong type argument: listp, #<marker at 4045 in hanoi.el>
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.
