Comment(by craigcitro):
Okay, I've attached a patch. The issue is that we can't coerce from NTL
into a finite field.
This patch isn't anything too clever -- I just do the naive thing and work
over the base ring from the start instead of using NTL. It runs at the
same speed for `100000` terms, and only loses about `3%` performance at
`1000000`, so this should definitely do the job. I'm happy to come back
and either unify these (maybe we don't need to manually use NTL anymore?)
or do some additional work to speed it up in the finite field case later
on.
