We have a crash which has been confirmed by at least two Ubuntu users with AMD64 processors, using Ubuntu's xemacs21-mule 21.4.21-1ubuntu3.1 (for Hardy). See http://tracker.xemacs.org/XEmacs/its/issue430 for details. I'm look for somebody with a fairly recent Ubuntu/AMD64 system who can help with debugging this. I'd be happy to give advice via IRC or similar, but what needs to be done at this point is fairly straightforward: (1) verify the bug using the recipes in the tracker on a vanilla Ubuntu installation; (2) check to see if the bug occurs for xemacs -vanilla and (for the Cyrillic case) xemacs -no-autoloads; (3) rebuild XEmacs 21.4 with the Ubuntu patches but using the normal XEmacs build process instead of debian/rules, and check if the bug occurs; and (4) rebuild with Ubuntu patches but with -g -Os (instead of -Owhatever), and check. Of course all of the runtime tests should be done under the debugger to compare backtraces of the crashes.
