We already have autosave-on-crash already, actually. The one catch is
that for crashes due to failed assertions (like this one), it isn't
triggered yet.
(I'm CCing the development mailing list, if anyone's interested in
attacking this right now:
At least on Unix, this is relatively easy to fix -- just set up a
SIGABRT handler similar to the SIGSEGV handler we have now. The one
catch is that the handler will need to disable itself as soon as it is
triggered, because the autosave code raises SIGABRT when it is done.
Also we should make sure we've got SIGBUS covered if we don't already.)

That looks just about right. The comment isn't very descriptive,
though. Maybe something more like "permit subsequent SIGABRT to dump
core"?
Feel free to commit, in any case.

Just out of curiousity - did this happen to get implemented?
