[Bug: 21.4.19] Xemacs Unstable on 64-bit Systems

Kenneth Loafman writes: Talk to Ubuntu about that; we don't produce executables for *nix at all. If you want to try to help debug them, enable core dumps, and get the symbol tables for XEmacs so you can produce useful backtraces. (AFAIK all distros strip those tables out of the distribution binaries, but many distros have an optional debug package which can be used to get useful traces.) The first thing I suggest trying is to build from our sources (not Ubuntu's). You may wish to check any patches they provide to see if they seem to make sense. You should upgrade to 21.4.20; there have been some crashes fixed since then. The code base of 21.4 was developed when 64-bit machines were quite rare. A lot of effort was put into making it 64-bit ready, but GCC has also changed a lot since 2.95, and there may be gotchas that could not be anticipated. Pay careful attention to all warnings, as any of them could indicate a problem. Redirect the compiler output to a file, and use M-x build-report to send us a build report which will include those warnings. (You'll need to M-x customize-group RET build-report RET to point build-report at your build log.) Finally, you might want to consider using the 21.5 series instead of 21.4; I use XEmacs 21.5 heavily on an amd64 system, with no problems of generally flaky instability. (OTOH, that is the development branch and suffers from general immaturity and occasional new-code-induced instability.) _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
