Drew, does this allow to identify potential villains? We are looking
for some code that runs inside the above 2 forms.

Corrupted stack is not the issue. AFAIU, we are looking for some C
code which doesn't balance specbind/record_unwind_protect with the
corresponding unbind_to. This code could be executed by some
primitive, or some C function called from some primitive, that is
invoked from Lisp. The problem is to find that Lisp. I hope Drew
will be able to, given the above hints.
