All planes are clipped by the same box. The red "circle" show the broken 
lines in the resulting scene which is attached.

Here is the script (the resulting scene is attached):

global_settings { assumed_gamma 2.2 }
sky_sphere { pigment { rgb <0.20,0.20,0.20> } }
light_source { <8.,8.,1.84e+01> color rgb <1.,1.,1.> }
light_source { <-8.0,-8.0,1.840e+01> color rgb <1.,1.,1.> }
camera {
   location <0.0,0.0,8.4>
   right -x
   look_at <0,0,0>
  angle 45
}
plane { 
<-8.164965809277258e-01,4.714045207910321e-01,3.333333333333335e-01>, -1.0
   clipped_by { box { <2.1,2.1,2.1> <-2.1,-2.1,-2.1> }}
   texture {

     finish { phong 0.700000 ambient rgb <0.70,0.70,0.70>}

No matter how hard I try I see nothing red in the attached image. And 
can you post a _minimal_ scene showing the problem. By minimal I mean 
that there should be no unnecessary lights, finish or transmit 
statements, objects (for example if you need only _one_ plane to show 
the problem, now there are 4 of them) or sky_spheres etc. Try to make it 
as small and simple as possible. That would make it easier to spot the 
actual problem and maybe even solve it. Thanks in advance.

Change color of the planes to realize you are confused by the shadow of one of
planes.

OK, I got it, this is not a bug !!

This is a shadow looking exactly as the object itleft (because the is 
only ambient light) making: the real intersection line between the two 
plane invisible !!!

Sorry

That's okay, man; we don't judge the chromatically challenged here. We're
all god's creatures :-P
