The second argument to scan-sexps is a count, not position, so you might want to
rethink that example.
Anyway, I'm not seeing any problems. I built the emacs-26 branch and ran the
shell command:
src/emacs -Q lisp/woman.el
and then typed:
M-: (scan-sexps (point-min) (point-max)) RET
and it returned nil, which is what I'd expect. Can you reproduce the problem
with a simple, self-contained test case like that?
