Testing out ispell-word caused xemacs to hit the following abort in redisplay.c (line 6615): start_elt = point_in_line_start_cache (w, cur_start, 0); if (start_elt == -1) abort (); /* this had better never happen */ Well, it *did* happen. -- Glynn Clements <glynn(a)sensei.co.uk&gt; xemacs: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 40 (X_TranslateCoords) Resource id in failed request: 0x8000e1 Serial number of failed request: 331334 Current serial number in output stream: 331334 Fatal error: assertion failed, file redisplay.c, line 6615, abort() 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/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.)
