GNU Emacs 18.51 running under Sun UNIX Release 3.5 on a Sun 3/60. The function looking-at fails inappropriately. Repeat by running "emacs -q", using M-x load-file to load a file containing this function definition: (defun bug-test () (interactive) (set-buffer (generate-new-buffer "*BUG TEST*")) (insert "\200") (forward-char -1) (if (looking-at "\200") (message "looking-at bug not present") (message "looking-at bug present on your system")) (kill-buffer (current-buffer))) and then running M-x bug-test. I have reproduced the buggy behavior only on Suns, a 3/60 and a 3/160, both running release 3.5. The bug does not appear on our Vaxen, but they are running version 18.52 under Ultrix 3.0. If you put (setq case-fold-search nil) just before the call to looking-at, the buggy behavior goes away.
