I'm going to log this as a confirmed bug, even though I'm not entirely
sure of the conditions under which the shadows are present.

On my system there are no shadows in either of the examples posted.

Here's my, rather confusing, contribution to the fray - no text object,
just spheres and boxes for simplicity.



camera { location  <0, 2, -3>
         look_at   0
}
    
light_group {
  light_source { <-1, 3, 1> rgb 1}
  sphere {y,0.5 pigment {rgb 1}}
  box {<-1,0,-1><1,0.5,1> pigment {rgb 1}}
}

//  sphere {<4,-5,10>,0.5 pigment {rgb 1}}

background {rgb z}



On my machine, as written, the sphere casts a shadow on the box.
However, when I uncomment the second sphere the shadow disappears. The
existence of any extra object seems to switch off the shadow. Even if
the second sphere is moved inside the light group it kills the shadow.
