In XEmacs 21.0 "San Clemente" [Lucid] (i386-pc-cygwin32) of Tue May 26 1998 on MAPLE configured using `configure --site-includes=/usr/local/include --site-libraries=/usr/local/lib' I'm still trying to figure out how to get Cygwin32 GDB to run, so I can't provide further information at the moment.... maple% uname -a CYGWIN32_NT MAPLE 4.0 19.2 i686 unknown maple% printenv DISPLAY 127.0.0.1:0.0 maple% /usr/local/bin/xemacs-21.0-b41.exe -vanilla -f make-mswindows-device Fatal error: assertion failed, file event-unixoid.c, line 153, CONSOLE_TTY_P (con) 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-21.0-b41.exe 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: make-device(mswindows nil) make-mswindows-device() # bind (arg) command-line-do-funcall("-f") # bind (dir file-count line end-of-options first-file-buffer file-p arg tem) command-line-1() # bind (command-line-args-left) command-line() # (unwind-protect ...) normal-top-level() # (condition-case ... . error) # (catch top-level ...)
