I'm able to reproduce this in a fresh HOME (I've tried with versions
25.3 and 26.0.91), with the attached init.el.

[Message part 3 (text/plain, inline)]

It looks like there is a Lisp_Misc_Free object in the undo-list. At
least, I think it's the undo-list.  One time I actually got the
mark_object (BVAR (nextb, undo_list)) in the backtrace, although the
next time it was just mark_stack, but the object being marked still
looks like an undo-list.
