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 21.2 (beta23) "Hebe" [Lucid] (sparc-sun-solaris2.6) of Sat Dec 11 1999 on ebola configured using `configure --prefix=/pkg/gnu --dynamic --with-gcc '--cflags=-O3 -mv8 -mtune=ultrasparc' --with-x --with-xpm --x-includes=/usr/openwin/include '--site-includes=/usr/dt/include /pkg/X11/include /pkg/local/include /pkg/local/include/db' --x-libraries=/usr/openwin/lib '--site-libraries=/usr/dt/lib /pkg/X11/lib /pkg/local/lib' --with-sound=native --with-database=berkdb,dbm --with-png --with-jpeg --infopath=/pkg/gnu/info:/pkg/local/info:/pkg/tetex/info --with-tooltalk=yes --with-cde=no --package-path=/pkg/gnu/lib/xemacs/packages --with-mule=no --debug=no --error-checking=none' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: I was editing few java files.In dired mode the buffer names are shown as tabs on the top of the window. I switched from one buffer to another by clicking on the tab. Xemacs dumps core. Error message and Stack trace is as follows: click 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 /pkg/gnu/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.)
