Comment (by jpflori):
This is caused by the "fix" I proposed before to return IntegerMod(1) for
algebraic extension of IntegerMod(1), because now I feel a common parent
is chosen as IntegerMod(1), but this is a prime field and the element from
the extension field "cannot" be cast there.
A proper solution could be to investigate the infinite loop we get when
the ArithmeticError is replaced with returning a unit when computing 0^0.
Another solution might be to forbid extension of IntegerMod(1) so that we
don't get crappy common parents.
