P3DFFT stands for Parallel Three-Dimensional Fast Fourier Transforms. It is a library for large-scale computer simulations on parallel platforms. It implements 3D FFT and related algorithms such as Chebyshev transform (an important class of algorithm for simulations in a wide range of fields). P3DFFT uses 2D, or pencil, decomposition.

I already created a pull request (which got pulled) some time ago, but the problem re-appears.
When upsampling in k-space is used, we call the setup several times - which fails, even after p3dfft-free call, since some variables are not deallocated on free
