That error popped up. I cannot reproduce this with stock Emacs 27.1, but I can reproduce with the current emacs-27 branch. The more detailed error message is this: Eval error in the ‘c-lang-defvar’ or ‘c-lang-setvar’ for ‘font-lock-comment-end-skip’ (fallback source eval - js-mode compiled with CC Mode 5.34 but loaded with 5.34.1): (error "‘c-font-lock-comment-end-skip’ got no (prior) value in js-mode (might be a cyclic reference)") Alan, can you take a look, please?
