well, i meant what does it compile when it's already loaded -- in response 
to events in REPL.

i've found single place where it does (compile nil:

(let ((regex-hash (make-hash-table :test #'equal)))
  (defun compiled-regex (regex-string)
    (or (gethash regex-string regex-hash)
        (setf (gethash regex-string regex-hash)
              (if (zerop (length regex-string))
                  (lambda (s) (check-type s string) t)
                  (compile nil (slime-nregex:regex-compile 

i suspect it's highly likely that ABCL chokes on attempts to compile some 
regex function.. but it's not that simple -- possibly it's superposition of 
several bugs in ABCL :).
