Today, my emacs 18.55 (on a VAX) died with signal 4. I did emacs -f
rmail, examined my messages, did M-x gnus (3.13 with small changes),
and emacs died while still in the startup phase (that is, before
popping the *Newsgroups* buffer). I managed to recreate it once; then I
started emacs again without the flag "-f rmail", M-x gnus worked, and
subsequent attempts to recreate the dump failed.

The core suggests that a garbage-collection kicked in at the wrong
moment (see stack below). Now, I've been a bit sloppy about archiving
bug reports <blush>, so maybe this has been solved long ago. If so,
I'd be grateful if someone enlightened me. Recreating the dump will
probably be difficult since it seems to depend on GC timing. I still
have the core. Details on request.
