I had to do the following to re-create this error.
emacs --batch --eval "(progn (add-to-list 'load-path \"~/src/org-mode/lisp\") (require 'org) (add-to-list 'load-path \"~/src/org-mode/contrib/lisp\")(require 'htmlize))" --visit /tmp/cpp-test.org --funcall org-html-export-to-html

I think this may be a bug in cc-mode when run in a batch Emacs session.
My guess is that the `c-standard-font-lock-fontify-region-function' is
never set. You could either try to set this value manually, or report
this to the cc-mode maintainers, but I wouldn't be surprised if they ask
why you want fontification in a batch session.
Setting this variable manually from the command line with the following
fixes this problem for me.
emacs --batch --eval "(progn (add-to-list 'load-path \"~/src/org-mode/lisp\") (require 'org) (add-to-list 'load-path \"~/src/org-mode/contrib/lisp\")(require 'htmlize) (setq c-standard-font-lock-fontify-region-function 'font-lock-default-fontify-region))" --visit /tmp/cpp-test.org --funcall org-html-export-to-html
Cheers,
