The copy of the bug code you sent me got garbled as follows:

(defun =sample2 (n)
  (macrolet ((f (result x)
                `(list 'more (lambda () (=f ,result ,x))))
             (g (result x)
                `(list 'more (lambda () (=g ,result ,x)))))
    (labels ((=f (result x)
               (if (zerop x)
                 result
                 (g (1+ result) (1- x))))
             (=g (result x)
               (f result x)))
      (f 0 n))))


I assume that one is supposed to remove all the #\= characters?

It's exactly the code that was sent to me. I think the point is that the macrolet conceils the fact that the "=g" function is being called through the "g" macro and that ABCL incorrectly handles the situation as dead code.
