In XEmacs 21.2 "Aphrodite" [Lucid] (mips-sgi-irix6.3, Mule) of Fri Dec 11 1998 on xiphias.pdc.kth.se configured using `configure --with-mule --package-path=/usr/local/vol/xemacs-21.2.5/lib/xemacs --site-includes=/afs/pdc.kth.se/src/packages/gnu/libpng-1.0.2/sgi_63 --site-libraries=/afs/pdc.kth.se/src/packages/gnu/libpng-1.0.2/sgi_63 --prefix=/usr/local/vol/xemacs-21.2.5' I was reading a article in Gnus. Fatal error: assertion failed, file /afs/pdc.kth.se/src/packages/gnu/emacsen/xemacs-21.2.5/xemacs-21.2.5/src/insdel.c, line 364, VALID_CHARPTR_P (ptr) Fatal error (6). Your files have been auto-saved. Use `M-x recover-session' to recover them. 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/vol/xemacs-21.2.5/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.)
