Only occurs with beta 7 and gives different results different with the
intel and msvc compile. 

Sample code:

camera {
  orthographic
  location <0,0,1>
  look_at  <0,0,0>
  right 1*x
  up 1*y
}

box {
  <-0.5, -0.5, 0>, <0.5, 0.5, 0>
  texture {
    pigment {
      agate
      color_map { [0 rgb 0][1 rgb 1] }
    }
    finish { ambient 1 diffuse 0 }
  }
}

There was some code that used this formula:
    value = (2.0 * Noise(EPoint, TPat)) - 0.5;
and I wanted to correct it so it looked like this:
    value = (2.0 * Noise(EPoint, TPat) - 0.5);
but I goofed and pasted this in instead:
    value = (2.0 * Noise(temp, TPat) - 0.5);

The value of "temp" was undefined at this point in the funciton, so noise
was usually result.

Is it the same reason that the marble pattern in White_Marble is
messed up?

Nevermind, just saw that it is listed as a known bug.
