Hi, First I compiled XEmacs 21.5 (beta9) with this option: and all works great. But then I tried to use the new external widget function and compiled with: Since then I get this error message if I close a xemacs.: ----------------------------------------------------------------------------------- Fatal error (11). Your files have been auto-saved. Use `M-x recover-session' to recover them. If you have access to the PROBLEMS file that came with your version of XEmacs, please check to see if your crash is described there, as there may be a workaround available. Otherwise, please report this bug by running the send-pr script included with XEmacs, or selecting `Send Bug Report' from the help menu. As a last resort send ordinary email to `crashes(a)xemacs.org&#39;. *MAKE SURE* to include the information in the command M-x describe-installation. If at all possible, *please* try to obtain a C stack backtrace; it will help us immensely in determining what went wrong. To do this, locate the core file that was produced as a result of this crash (it's usually called `core' and is located in the directory in which you started the editor, or maybe in your home directory), and type gdb /usr/local/bin/xemacs core then type `where' when the debugger prompt comes up. (If you don't have GDB on your system, you might have DBX, or XDB, or SDB. A similar procedure should work for all of these. Ask your system administrator if you need more help.) Lisp backtrace follows: # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) kill-emacs() # bind (arg) save-buffers-kill-emacs() delete-frame(#<x-frame "emacs" 0xc749> t) eval((delete-frame #<x-frame "emacs" 0xc749> t)) # (condition-case ... . error) # (catch top-level ...)

Do I need to activate the core-file ability before? If I exec xemacs with gdb this is printed: ... Starting program: /usr/local/bin/xemacs-21.5-b9 Program exited normally. ... Why is here no "Segmentation fault"? Is this a correct list for beta bug reports or is there a better one? Thanks Andreas
