bug with usocket and/or trunk ccl - "error #22"

[Mark H. David]

This works on an earlier CCL:
  Welcome to Clozure Common Lisp Version 1.10-r16196  (LinuxX8664)!

(let* ((host "localhost")
       (port 1111)
       (server-sock
         (usocket:socket-connect nil nil :protocol ':datagram :local-host host :local-port port))
       (client-sock
         (usocket:socket-connect host port :protocol ':datagram))
       (octet-vector
         (make-array 2 :element-type '(unsigned-byte 8) :initial-contents `(,(char-code #\O) ,(char-code #\K))))
       (recv-octet-vector
         (make-array 2 :element-type '(unsigned-byte 8))))
  (usocket:socket-send client-sock octet-vector 2)
  (usocket:socket-receive server-sock recv-octet-vector 2)
  (prog1 (and (equalp octet-vector recv-octet-vector)
              recv-octet-vector)
    (usocket:socket-close server-sock)
    (usocket:socket-close client-sock)))

=>

#(79 75)



On trunk CCL, updated/built on 5/19/15: 
  Welcome to Clozure Common Lisp Version 1.11-dev-r16393M-trunk  (DarwinX8664)!

It gets an error:

> While executing: (:INTERNAL SWANK::INVOKE-DEFAULT-DEBUGGER), in process repl-thread(12).
> Type :POP to abort, :R for a list of available restarts.

What's up with that?
