Hi superpatchers,

the following code (a simple sky sphere, 2 lights and some water)
sends the latest superpatch (here on Solaris 7, linux not yet
tested) into an endless loop. If I remove the reflection statement
right at the end of the code all is ok.

Any ideas?

Scene follows:

#include "colors.inc"

#declare camera_location = <26, 4.3, -80>;
#declare camera_look_at  = <17, 0, 0>;
#declare camera_angle    = 120;


/*******************************
 * THE CAMERA
 *******************************/
camera{
  location camera_location
  look_at camera_look_at
  angle camera_angle
}


/*******************************
 * THE SKY
 *******************************/
#declare SkyBlue = rgb <0.15, 0.4, 0.7>;
#declare P_Clouds =
pigment {
  wrinkles
  turbulence 0.1
  lambda 2.2
  omega 0.707
  color_map {
    [0.60 SkyBlue ]
    [0.80 White ]
    [1.00 Gray90 ]
  }
  scale <0.5, 0.15, 1>
  rotate  z*180
}
sky_sphere {
  pigment {
    gradient y
    pigment_map {
      [0.00 rgb <0.847, 0.749, 0.847> ] // horizon
      [0.05 SkyBlue ]                   // horizon
      [1.00 SkyBlue ]
    }
  }
}


/*******************************
 * THE LIGHTS
 *******************************/

light_source { <450, 350, -200> colour rgb 3.4*<1.0, 1.0, 1.0> }
light_source { <-1300, 100, 300> colour rgb 0.7*<1.0, 1.0, 1.0> }


/*******************************
 * THE WATER
 *******************************/

plane { y, 0.0
  texture {
    pigment { color rgbt <0.0, 0.1, 0.1, 0.5> }
    finish {
      ambient 0.15
      brilliance 5
      diffuse 0.6
      metallic
      specular 0.80
      roughness 1/100
      reflection 1.0 // <--- this one is the guilty
    }
    rotate y*90
  }
}

It doesn't break on my Windows build at work.  I'll have to see what
it does on Linux, but my debugging skills are not so hot there so it
might take a while.  If someone felt so inclined, they could
investigate this... :)

I could reproduce it on linux, too. It happens with the
latest superpatch as well as with my upgrade to 3.1g.
Sorry, I had not enough time to go more into details as I'm
presently in a similar situation like you ;-)
I'm not too familiar with the reflection code.
