I think that Taylor expansions are okay because they are smooth. The issue pertains only to basis functions that are singular (like Bessel functions of the second kind). |

Taylor multipoles aren't smooth though. (The multipole basis consists of derivatives of the kernel.) |

If the expansion basis is singular at the origin, and a source point lies at the expansion center,
p2efails with NaNs.The added test shows that this is indeed an issue with
