Hi, Alesio

Oh, sorry, maybe I didn't say it clearly, the "Register 4 contains wrong type" is not produced by the file with THREADS:WITH-MUTEX. It's another issue, not relevant to the first post in this mail thread.

Following function caused the "Register 4 contains wrong type" issue:

(defun generate-table (vars vbs non-repeaters max-repetitions)
  (declare (type fixnum non-repeaters max-repetitions))
  (let* ((var-number (list-length vars))
         (n (min non-repeaters var-number))
         (m max-repetitions)
         (r (max (- var-number n) 0))
         (real-vbs (mapcar #'(lambda (x) (coerce x 'list))
                           (coerce vbs 'list)))
         result-table)
    ;; non-repeaters
    (dotimes (i n)
      (push (pop real-vbs) result-table))
    ;; table
    (when (and (plusp m) (plusp r))
      (dotimes (i m)
        (push (let (record)
                (dotimes (j r (nreverse record))
                  (push (pop real-vbs) record)))
              result-table)))
    (values (nreverse result-table)
            (mapcar #'oid vars))))

If I temporary disable it by #+ignore or #-abcl, than the whole project compiles with no error any more. I'll try to continue look for which exactly form in this function caused the error.
