syntax-propertize-function:

" ...
The specified function may call ‘syntax-ppss’ on any position
before END, but it should not call ‘syntax-ppss-flush-cache’,
which means that it should not call ‘syntax-ppss’ on some
position and later modify the buffer on some earlier position."

Source of

(defun syntax-ppss (&optional pos)
  " [ ... ]"
  ;; Default values.
  (unless pos (setq pos (point)))
  (syntax-propertize pos)
