Hi,

a user of Hunchentoot has reported problems with Clozure CL and MD5, and I was able to track this down to a problem in CCL (tested with 1.8 on Linux):

Welcome to Clozure Common Lisp Version 1.8-r15286M  (LinuxX8632)!
? (defun foo ()
  (let ((block (make-array 16)))
    (loop for index of-type (integer 0 16) from 0 below 16
          do (print index)
             (setf (aref block index) #x00000000))))
FOO
? (foo)

If the type declaration in the loop is omitted, the problem does not occur.

It should be possible for gf dispatch to run simultaneously in multiple threads without introducing inconsistencies in CLOS internals (e.g. caches).

FWIW, here's what sbcl does about this: ​http://lisp-ecoop07.bknr.net/pdf/31662.

In the IDE listener:

? (ed "~/.emacs")

Error: This implementation doesn't provide a resident editor. While executing: ED, in process Listener(4). Type :POP to abort, :R for a list of available restarts. Type :? for other options.
