17 ;;; Hannu Rummukainen reported a CMU CL bug on cmucl-imp@cons.org 26
18 ;;; Jun 2000. This is the test case for it.
20 ;;; The bug was listed as "39: .. Probably the same bug exists in
21 ;;; SBCL" for a while until Martin Atzmueller showed that it's not
22 ;;; present after all, presumably because the bug was introduced into
23 ;;; CMU CL after the fork. But we'll test for it anyway, in case
24 ;;; e.g. someone inadvertently ports the bad code.
