Hello, Martin.

I am calling:
emacs -Q --eval "(progn (add-hook 'prog-mode-hook #'font-lock-fontify-buffer)
(setq debug-on-error t))" ~/emacs/emacs.bzr/trunk/src/xdisp.c
using both emacs 24.3 and the trunk. In 24.3, the processing is
immediate (~2s), whereas in the trunk it takes ~28s.

In both 24.3 and trunk, `font-lock-fontify-buffer-function' ends up with
the value `jit-lock-refontify'.

I don't understand what you mean by "from c-mode" and "from prog-mode".
Are you saying that that has somehow changed between 24.3 and the trunk?
