For some kernels like e.g. gaussian, a near field regularization is not required in fastsum (near field size eps_I = 0) and consequently, the near field correction computations may be omitted. Currently, precomputations are still performed in this case.
Moreover, in case of NEARFIELD_BOXES, a division by zero occurs for eps_I = 0 in fastsum_init_guru_source_nodes.
