It's because of this snippet from font-lock.el:

  (defconst lisp-font-lock-keywords-2
    (append lisp-font-lock-keywords-1
     (eval-when-compile
     ...
         ;; Erroneous structures.
         
("(\\(abort\\|assert\\|warn\\|check-type\\|cerror\\|error\\|signal\\)\\_>" 1 
font-lock-warning-face)

Not sure what this is supposed to catch.
