For the record, there was no bug with POV-Ray in this case.  (See my post to
Sigmund's other post.)  In this case, the user-defined function was trying
to take the square root of a negative number, which is not defined as a real
number.  I don't know why it worked with MegaPOV, because it shouldn't have.
