Folks, Looks like with progress-feedback-use-echo-area "on", under Mac OS X (fink installed) version of Xemacs 21.4.15, the mercury gauge kills the process. Turning off the progress-feedback-use-echo-area works around the problem. I am not sure if this is the same as reported in the PROBLEMS file, but I figured I would update you folks anyway. Let me know if you need anything else. Thanks, -Peter Fatal error (10). 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 necessary, send ordinary email to `crashes(a)xemacs.org&#39;. *MAKE SURE* to include 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 /sw/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. Lisp backtrace follows: dispatch-non-command-events() # (condition-case ... .
