Unfortunately, there is nothing unusual in any log file around the
time of the timestamp of the auto-save file, which I assume is close
to the time of the crash.

My system is in fact set up not to create core files, but I can change
that.  Can you recommend a reasonable maximum size?

It appears in this case to be the latter.  FWIW, I still have the
auto-save file, but even compressed it's bigger than 13MB, so I don't
want to attach it.  Anyway, I doubt it's useful, but just to get an
idea of it, I've attached the first 95 lines.
