Description
This bit of code causes a bug in tracing on Darwin/x86:
(defun call-fact-acc (x) (let ((r (multiple-value-list (fact-acc x)))) (values-list r))) (defun fact-acc (x) (labels ((f (x accum) (if (zerop x) accum (f (1- x) (* x accum))))) (f x 1))) (trace fact-acc)
Then (call-fact-acc 4)
causes a segfault and you can't even get back to the repl.
This bug is fixed in CVS, but I'm recording this simple test case here.
