Re: [Bug:21.4.16] regex.c and xemacs hangs.

You can revert locally if you like. However, I can't reproduce on Linux or Mac OS X, I can find nothing wrong with the logic. Please be aware that XEmacs without the patch is *broken*. The patch fixes a real bug that causes many regexps containing shy groups to match incorrectly. Unfortunately there are many applications that use shy groups; we cannot assume that they won't be present. Until there are further reports or a developer can reproduce, the situation is unlikely to change very quickly. In the meantime, have you reproduced with xemacs -vanilla? This is very important; there is an unrelated bug that causes infloops for regexps that specify a repeated zero-length match. This bug is not yet fixed. So you may have a save-hook that invokes such a regexp. Can you get a backtrace for the hang? 1. Set debug-on-quit on before saving, then C-g at hang should give a trace. 2. Run XEmacs under the debugger, hang XEmacs, suspend XEmacs, then use the debugger to get a C backtrace. 3. If 1 didn't work, then at this point "ldp" should give a backtrace, too. Are you running an XEmacs built from a fresh checkout? Is it possible that you are missing a patch? (There were _two_ patches related to this, the first fixed most of the bug, and the second picked up a hunk that somehow got dropped from the first patch). -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
