What were you trying to do?
Test some elisp code in /mit/outland/lib/elisp/new. I ran emacs -q,
edited ~outland/lib/elisp/w3-setup.el, saved it as
~outland/lib/elisp/new/new-setup.el, eval-current-buffer'd it, and
then ran w3-fetch on http://rr1.lcs.mit.edu:8001/ (a test server I
run)
What's wrong:
It responded normally for a while, and then died scrolling a buffer:
pid 18619 (emacs) was killed on an unaligned access, at pc 0x44f2f4
[3] Bus error emacs -q (core dumped)
; gdb /usr/athena/bin/emacs core.emacs

To repeat, run emacs -q, load the file and run w3-fetch as mentioned
above, and hit:
f RETURN s y RETURN (you'll get a `not responding' error here)
s y RETURN (watch errors like the following some up in your
shell:

go into your shell, hit return, be told that emacs dumped core.)
two of these (proabbly useless) corefiles are in
~yandros/tmp/core.emacs.930712[-1].gz; please tell me when I can
remove them, as I doubt they'll be useful to you...
