Macintosh Performa 6400 with Sonnet Crescendo G3 Card
RAM : 80Mb, 24Mb allocated to PovRay
System 9.1 (french)
CarbonLib 1.3.1
POV-Ray Mac 3.5 beta 1


I'm trying to render the simili-glow example
posted by Warp in povray-beta-binaries two days ago.
It crashes Povray beta 1 (type 2 error) right
after the image is finished : the output file is
written on disk, but the job terminaison sound is 
not yet played.
Rendering settings are set to "Default". I have 
tried both PICT and PNG output file format, the
crash occurs for both. 

Hope this helps,
Stephane.



Here is Warp's glow code :

------------------------------------------

#macro Glow(GlowColor, Scale)
  sphere
  { 0, 1 hollow no_shadow
    pigment { rgbt 1 }
    interior
    { media
      { emission 1/Scale
        density
        { spherical density_map
          { [0 rgb 0][.5 rgb GlowColor*.5][1 rgb 1]
          }
        }
        samples 1,1 intervals 1 confidence .1 // quite fast settings
        method 3
      }
    }
    scale Scale
  }
#end

camera { location -z*10 look_at 0 angle 35 }
plane { y,-2 pigment { checker rgb 1, rgb .5 } }

light_source
{ <-1.5,1,0>, <1,.5,0>
  looks_like { Glow(<1,.5,0>, .5) }
}
light_source
{ <2,.5,0>, <0,.5,1>
  looks_like { Glow(<0,.5,1>, 1) }
}

In fact, it looks as if all the media scenes from the "media" folder
crash Povray.

I tested the scene with the latest 3.5 beta and didn't have any problem,
so it either has to be a mac-related issue, or else there's some type of
memory leak that causes it to crash (reading/writing outside allocated
memory has the odd behaviour that it can crash in one system and not in
another even when it's wrong in all systems).

I've just tried one Media scene yet; "micro.pov". The same problem for
me. Type 2 error after the image had been rendered.

This observation is correct.  There is a small but significant bug in the
render stats output that destroys the stack.
