Divide curve by distance fail

In the definition that i have, when a certain number is used in the divide by distance component, the division fails and divides only a part of the curve. It normally works fine, but in one range, it fails.

What is the reason for this?

*edit*

the last index in the list is {NaN,Nan,NaN}. Sounds like that indian bread which is quite yummy.

NaN is short for "Not A Number" which is a special mash-up of the bits inside a floating point number that indicates an invalid number (PositiveInfinity and NegativeInfinity are other special cases that don't play nice with proper numbers).

DivideDistance works by intersecting the base curve with a sphere centered around the previous intersection point. If this intersection fails (which, let's face it, isn't unheard of in Rhino) then the points will be cut short.

If you can post the curve that fails I can have a look at what might be done.
