Comment:
As mentioned in one of the sage-devel threads linked above, the issue here
is that `ZZ` assumes that if it's the parent of some `x`, then `x` is of
type `sage.rings.integer.Integer`. (Similar assumptions are made all
over.) It turns out that this popping up only on OSX was a weird artifact
of compiler details/how memory is initialized/the alignment of the
planets, as explained in the sage-devel thread.
I'm waiting for Nicolas to weigh in on what he thinks should happen with
the `ElementWrapper` code -- he's probably the most appropriate person to
spin a patch. (Nicolas, I'm adding you in the cc.)
