Well, I've been aware of that for some time know but unfortunately I
don't know how to fix it.  The backslash has escape syntax which seems
to override the syntax property placed at the position following it.
This will lead to `parse-partial-sexp' not finding the correct end of
the \verb construct.  I don't know if there is a way to get rid of the
backslash's escape syntax in verbatim commands/environments, or how to
make `parse-partial-sexp' ignore it.

Here is some code in case somebody wants to experiment:

(with-temp-buffer
  (insert "foo +\\+ bar")
  (put-text-property 5 6 'syntax-table '(15))
  (put-text-property 7 8 'syntax-table '(15))
  (goto-char (point-min))
  (set (make-local-variable 'parse-sexp-lookup-properties) t)
  (let ((old-state (parse-partial-sexp (point-min) (point-max)
				       nil nil nil 'syntax-table)))
    (parse-partial-sexp (point) (point-max)
			nil nil old-state 'syntax-table))
  (point))

Note how the value returned changes upon replacing the "\\" e.g. with
"a".
