The following file crashes my version of 3.1b5, but
renders successfully when I omit the color_map
statement.  I have reported this to win### [at] povrayorg .

I received the following generous reply to my bug report
from one of the POV developers:

  The crash is because you have both a density_map and a color_map.
  In fact color_map should not go with average.  You need to make two    
color maps: put one in granite and one in bozo.  

  I've put it a trap for this so that next time it'll give you an
  error message.
