This one is _really_ annoying.
I'm getting core dumps anytime I do something to a region.
Recipe for crash:
C-SPC
move point somewhere to create a region
C-w (M-w works just as well, even M-x boxquote-region)
CRASH!
Okay, I don't know anything about gdb (never been inspired enough to
learn), but here's what I've been able to dredge up. I apologise if
it's not useful.

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-21.2-b44 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:
call-interactively(kill-region)
# (condition-case ... . error)
# (catch top-level ...)

it's not useful.
I'm hoping this one isn't my fault, although I have this fear that it
is. A stack backtrace in gdb (using 'bt' or 'where') would really help
to pin it down, though.
I find that when I get 'Cannot access memory at address ...' messages
from gdb, it's because it can't deal with the optimizations that were
enabled for that particular compile. So if you're having problems with
getting a clean backtrace, you might want to try turning off
optimizations and recompiling.
