This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.0 "Pyrenean63" [Lucid] (i686-pc-cygwin32) of Mon Feb 15 1999 on smithers configured using `configure --error-checking=none' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: I guess this has something to do with the fact that we can't currently have frame on both X and MSWINDOWS devices. Still, it probably shouldn't crash... smithers% uname -a CYGWIN_NT-4.0 SMITHERS 20.1 (0.3/1/1) 1998-12-3 20:39:18 i686 unknown smithers% echo $DISPLAY 127.0.0.1:0.0 smithers% xemacs -vanilla -eval "(make-device 'mswindows nil)" Fatal error: assertion failed, file event-unixoid.c, line 153, CONSOLE_TTY_P (co n) 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'. *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.)
