Cubic natural interpolation fails when interpolating three points in > 2D #226

Closed msteinbeck closed 1 year ago

The issue results from the following call:

memcpy(thomas, points, sof_ctrlp);

Here points overwrites itself because thomas contains only two values (a and b) before it overlaps with points.
