Can you figure out which slot, in which stack frame,
is currently being examined within mark_stack?  That would
probably lead us to the C level bug that directly causes
these crashes.

If we make changes at the Lisp level, the C-level bug may no
longer happen often in this way, but it will still remain and
may cause occasional crashes on other occasions.  So please try
to debug it now while the Lisp code still triggers it.
