Slightly more detailed version of the usual reply follows:
As usual, I can't reproduce this bug with my development version of POV-Ray.
I can reproduce it with POV 3.5 beta 6.
However, the reason for the bug occurring is beyond me: I just finished
comparing the spline source code for my development version, and the spline
source code for the official version, and they are virtually identical.
There are no differences that would be causing this problem.
