Re: [Failure] XEmacs 21.5-b23 "daikon" (+CVS-20051101) i586-pc-win32

Marcus> Thanks for testing, Malcolm! I'll try to reproduce this crash. Thanks! Now here are some more! I've been runninng your patch as my day-to-day XEmacs at work and today managed to get 4 crashes. After the first I started running it under gdb to get proper stack traces. If you need any more data then please let me know.

Your files have been auto-saved. Use `M-x recover-session' to recover them. Your version of XEmacs was distributed with a PROBLEMS file that may describe your crash, and with luck a workaround. Please check it first, but do report the crash anyway. Please report this bug by invoking M-x report-emacs-bug, or by selecting `Send Bug Report' from the Help menu. If that won't work, send ordinary email to `xemacs-beta(a)xemacs.org&#39;. *MAKE SURE* to include this entire output from this crash, especially including the Lisp backtrace, as well as the XEmacs configuration from M-x describe-installation (or equivalently, the file `Installation' in the top of the build tree). *Please* try *hard* to obtain a C stack backtrace; without it, we are unlikely to be able to analyze the problem. Locate the core file produced as a result of this crash (often called `core' or `core.<process-id>', and located in the directory in which you started XEmacs or your home directory), and type gdb /export/home/malcolmp/prefix/bin/xemacs core then type `where' at the debugger prompt. No GDB on your system? You may have DBX, or XDB, or SDB. (Ask your system administrator if you need help.) If no core file was produced, enable them (often with `ulimit -c unlimited') in case of future recurrance of the crash.
