I happened to be looking at the message pane, after rendering a typical scene
that includes only a single infinite object in it (a plane). Surprisingly, the
messages said '3 infinite objects' are in the scene. Trying to eliminate
possible causes, I came to this extremely simple result:

// the entire test scene(!)---
#version 3.71; // beta 9
global_settings{assumed_gamma 1.0}
sphere{0,1 scale 1358}
-----

At this scale (and larger), the message pane reports an infinite object! At
scale 1357, NO infinite object.

My first thought was, it must be an auto-bounding problem when using a
particular Bounding_Threshold. But no luck; that doesn't change it.

Yes indeed, very mysterious. Maybe the POV-Ray 'universe' shrunk down in size
while I wasn't looking :-P

v3.7.0 also does this.

Weird.

Currently, an object is considered infinite if its bounding box exceeds
a volume of 2.0e+10.
