The following results in a bad error under CCL 1.10 / Win64. it does work as expected under Win32 :

(defun define-char (character &rest data)
  (let ((chardata (make-array (list (length data) (length (car data)))
                              :element-type 'bit
                              )))
    (loop for m from 0
       for item in data
       do (loop for n from 0
             for bit in (coerce item 'list)
             do (setf (aref chardata m n) (if (zerop bit) 0 1))
               ))))

on osx 10.7.5.

when attempting to call send-to on a socket that already has remote-port/host or local-port set, ccl reports "socket is already connected (error #56) during send-to"

code example to tickle this problem ​http://paste.lisp.org/display/144678

after evaluating the defparameters calls to create the test vector and the socket, all three of the send-to calls fail with the same problem

Similar problems are encountered in python apparently. see ​https://github.com/zerovm/zerocloud/issues/86

The problem seems to be the lock-free version of clrhash not resetting nhash.grow-threshold.

? (let ((h (make-hash-table :size 100)))
    (format t "~&initial: ~s" (ccl::nhash.grow-threshold h))
    (dotimes (i 7) (setf (gethash i h) i))
    (format t "~&after use: ~s" (ccl::nhash.grow-threshold h))
    (clrhash h)
    (format t "~&after clrhash: ~s" (ccl::nhash.grow-threshold h)))
initial: 100
after use: 93
after clrhash: 93

Non-lock-free version works fine:

? (let ((h (make-hash-table :size 100 :lock-free nil)))
    (format t "~&initial: ~s" (ccl::nhash.grow-threshold h))
    (dotimes (i 7) (setf (gethash i h) i))
    (format t "~&after use: ~s" (ccl::nhash.grow-threshold h))
    (clrhash h)
    (format t "~&after clrhash: ~s" (ccl::nhash.grow-threshold h)))
initial: 100
after use: 93
after clrhash: 100
