 warning: Warning: GDB can't find the start of the function at
0xfb65c1c.

Yes, that is the C level backtrace!  It might be crashing in a system
call but neither gdb nor dbx can tell me.

I'm not using --unibyte and haven't deliberately turned it off, though
I haven't got around to installing leim.

Knew there was something I'd forgotten - the crash still occurs with
-q --no-site-file plus a little lisp to get vm and bbdb configured to
work together.  My configuration was included out of completeness.

I haven't yet tried to see whether it's caused by vm/bbdb interaction
but since it occurs in ediff as well that seems unlikely.
