Evaluating this expression causes a crash:

(progn
  (find-file (expand-file-name "src/treesit.c" installation-directory))
  (c-ts-mode)
  (font-lock-ensure 63209 63387))

in latest master, but not in latest emacs-29 (only in 5-months old emacs-29).

If this is not reproducible, I could provide more details.

libtree-sitter is at the latest version.
