Could you please show a complete recipe, starting from "emacs -Q"?
I'm afraid I don't understand from your description how to reproduce
the problem, in order to debug it.
It should be enough to provide some text to serve as buffer contents,
and a Lisp function to put the overlay on that text, such that Emacs
stops responding.
Thanks.
