The documentation should be a bit more clear about the size of those
arrays. My version tells me 'at least vc*2', but of course this will lead
to a horrible crash if more verteces are added.
Someone with better knowledge of 3D might know the exact number, but it's
more than vc*2.
Better be safe and use vc*clipping_planes or something like that.
