Hi(gh)!

I now have run mesh2writer.pov in various RAM configurations including 
only one 4 GB strip or one 8 GB strip in slot 1 - but always I got the 
memory access error in the 22nd outer iteration (at 1000 by 1000 data 
points; the number of the inner iteration varies wildly!) of the last 
nested loop:

#if (!(tilename="n80e014" | tilename="n80e016" | tilename="n80e017"))
   #declare i=0;
   #write (ES, "  texture_list")
   #write (ES, "  {\n")
   #write (ES, concat("    ",str(NumTextures, 1, 0),"\n"))
   #declare a=0;						
   // #declare c=0;
   #while (a<ydim)					// outer loop
     #declare b=0;
     #while (b<xdim)					// inner loop	
       #declare C_Texture = eval_pigment(P_Texture, 
<(0.5+b)*(1/(xdim-1)), (0.5+a)*(1/(ydim-1)), 1>);
       #warning concat("Iteration ", str(a, 1, 0), "-", str(b, 1, 0))
       #write (ES, "    texture\n")
       #write (ES, "    {\n")
       #write (ES, "      pigment\n")
       #write (ES, "      {\n")
       #write (ES, concat("	   color rgb <",vstr(3, C_Texture, ",", 1, 
7),">\n"))
       #write (ES, "      }\n")
       #write (ES  "	 finish{ F_Earthslice }\n")
       #write (ES, "    }\n"
       // #declare c=c+1;
       #declare b=b+1;
     #end
     #declare a=a+1;
   #end
   #write (ES, "  }\n")
#end

// end of code

I just can't figure out what should be wrong with this code - or is it 
just a bug in POV-Ray 3.7?

See you in Khyberspace!
