I don't have a fix, but here's a recipe that doesn't depends on c
mode.

;; emacs -Q

(defun test-bug-hook (overlay afterp beg end &optional r)
  (message "%s hook called" (if afterp "after" "before")))

(defun test-bug-after-change (beg end old-len)
  (remove-text-properties beg end nil))

(defun test-bug ()
  (interactive)
  (switch-to-buffer (get-buffer-create "*test*"))

  (kill-all-local-variables)
  (add-hook 'after-change-functions 'test-bug-after-change nil t)
  (setq font-lock-defaults '(nil t))

  (let ((beg (point)) ov)
    (insert "foobar")
    (setq ov (make-overlay beg (point)))
    (overlay-put ov 'face 'highlight)
    (overlay-put ov 'insert-in-front-hooks '(test-bug-hook)))
  (goto-char (point-min)))

(test-bug)

;; M-x eval-buffer RET
;; Insert char before overlay
;; => only before hook is called
