Interesting that it refers to my render script because it happened when 
I got over zealous with commenting out something in a material definition:

#declare Band_=
material {
	texture {  // uv_mapping
		//granite  <--- fat fingers
		poly_wave 2
		lambda 6
		turbulence 0.1
		scale 4
		warp { toroidal }
		texture_map {
			[0.0 Band2]
			[0.1250/5 Band1]
			[0.1250/5 Band1]
			[0.5 Band2]
			[0.5 Band1]
			[1.0 Band1]
			}
		}
	interior { ior 1.5 }
	}

technically it's not refering to your render script, but to internal 
data types ;)

I guess the parser doesn't like these in plain patterns for rather 
obvious reasons. But it shouldn't crash, that's for sure. I'll need to 
have a look at it.

This is actually not an UberPOV-specific issue at all; it's carried over 
from official POV-Ray.
