5:53 a.m.
When I ssh into my office computer and attach to a running xemacs
using the gnuclient program, but the attempt fails because of a
Kerberos authentication problem, xemacs crashes.
Here is the error message from gnuclient:
"X11 connection rejected because of wrong authentication."
Here is the crash message:
----------------------------------------------------------------
Fatal error: assertion failed, file
/afs/.cs.cmu.edu/misc/xemacs/src/core/xemacs-21.4.4/src/device-x.c, line 1119, d != NULL
Fatal error (6).
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'.
*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:
