It seems that introduced an infinite loop during fontification on a CCL source file. I'll investigate that later.
For the time being, please do not update to HEAD.
I committed a fix for that. I'd like if people could update to HEAD and try it on their .lisp files. Reader conditionals should now be suppressed accurately.
For the hopefully improbable case that you encounter an infinite loop, you can set `slime-highlight-suppressed-forms' to nil in your .emacs as a quickfix.
