Subject: 27.1; mhtml-mode eval errorr in c-lang-defvar or c-lang-setvar
Date: Sun, 09 Aug 2020 14:53:07 +0300

[Message part 1 (text/plain, inline)]

When html file is opened with the default html major mode mhtml-mode the
minibuffer will show this error message:

    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)") [2 times] mhtml-mode

I think this can be seen with any html file but I have attached a simple
"test.html" for testing.

    emacs -Q test.html

[test.html (text/html, attachment)]

I'm unable to reproduce this bug in Emacs 27.1 (or Emacs 28) -- with the
recipe, the buffer displays as normal, and I don't get any errors.

Now I completely cleaned my Emacs build directory and started again. The
reported bug don't appear anymore so it seems that this was some build
issue.

Sorry. I should clean the build directory more often, especially before
reporting bugs. I close this bug.
