I want to report a bug that looks strikingly similar to the bug reported by
Panagiotis Piperopoulos ( <368### [at] medauthgr> ).

In the attached and hereunder given *.pov file a height field is scaled.
Dependable on seemingly abitrary values of the scale vector POVray either
renders a picture or just crashes under windows 95.

Windows reports the following error msg:

The povray file:

// Standard pre-defined colors
#include "colors.inc"
light_source { <10,10,10> , rgb<1,1,1>
}

height_field {
    tga "kussen.tga"
    smooth
    scale <1,0.4,1>
    // whereas scale <1,1,2> produces no crash.
    pigment { White }
  }

camera
{
  location  <0.0 , 3.0 ,-2.0>
  look_at   <0.0 , 0.0 , 0.0>
}

For verification purposes:

This is repeatable on Pov 3.1.watcom.win32.r1 but does not occur on the
Pov 3.1d.msvc.win32 compile.
