The one for complex_pow(), I think accidently works for OP, but is likely broken for some general regions of the complex plane. > I'll open a separate bug for the FreeBSD issue.

The implementations are likely to be fairly direct without much optimization, worrying about exceptional casea, or even tested extensively.
