I have reported this bug some time ago and I gave solution for it for
MegaPOV but without sources I'm not sure it is exatly the same
problem.

Here is my solution:
http://news.povray.org/povray.unofficial.patches/7152/

And here is script to test it:

//<SDL>
  #local Step=.1;
  #local Obj=union{
    #local Counter=Step;
    #while (Counter<100)
      difference{
        sphere{0,Counter}
        sphere{0,Counter-(Step/2)}
      }
      #local Counter=Counter+Step;
    #end
  }
  #local Start=2*max_extent(Obj).x*x;
  #local Norm=<0,0,0>;
  global_settings{max_intersections 9}
  #local Inter=trace(Obj,Start,-Start,Norm)
  global_settings{max_intersections 99}
  #local Inter=trace(Obj,Start,-Start,Norm)
//</SDL>

ABX
