OK, here's another one.  At least they always differ by the same value.

I'm also puzzled by the

#3  0x01004620 in pure_write_error () at data.c:121

which should be wrong_type_argument (predicate, value).  I could send
you the Elisp code I use to trigger this.  You'd have to play around
with it a bit, though.
