Crash in XEmacs 21.0 "20 minutes to Nikko" with gnuserv/gnuclient
(This is the right place to send crash reports, right?)
I've got an easily-reproduceable crash in XEmacs 21.0 "20 minutes to
Nikko",
when using gnuserv/gnuclient. If I start xemacs, run gnuserv-start, flip to
another virtual console (this is on linux) run gnuclient, and then exit
gnuclient (with or without doing any actual editing), then xemacs on the
original virtual console barfs, with the following :
|Fatal error: assertion failed, file event-Xt.c, line 1863, closure
|
|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.)
|
|Lisp backtrace follows:
|
| kill-emacs()
| # bind (arg)
| save-buffers-kill-emacs(nil)
| # bind (command-debug-status)
| call-interactively(save-buffers-kill-emacs)
| # (condition-case ... . error)
| # (catch top-level ...)
The output from where in gdb is :

If anyone wants any more information, just let me know (I've got the
corefile copied).
