;;; Don Geddis reported this test case 25 December 1999 on a CMU CL
;;; mailing list: dumping circular lists caused the compiler to enter
;;; an infinite loop. Douglas Crosher reported a patch 27 Dec 1999.
;;; The patch was tested on SBCL by Martin Atzmueller 2 Nov 2000, and
;;; merged in sbcl-0.6.8.11.
