I've just hit another case of this crash in the same environment.
This time I was able to recover the post-mortem printout Vim itself
generated; may be it will be of use; especially, it appears we now have
the exact reason for the crash formulated by Vim:
--------------------------------8<--------------------------------

I have saved the core file, so I now have them both in case they may
come in handy -- just let me know.
