Sorry, read the wrong line in the last post..
I did a debug render on the Stack Overflow error, and found where it crashes.
Here is the code :
note: maxX = maxY = 200
Second test with maxX = maxY = 75 also crashes, at the number 42 this time.
a test with maxX = maxY = 50 worked...
Note : before this, 17 passes through the entire array was made, to calculate
the values.
/*useful for vector output */
#macro v2str(vVector)
concat("<", str(vVector.x,-1,10), ",", str(vVector.y,-1,10), ",",
str(vVector.z,-1,10),">")
#end
#macro WriteBoxes(sFilename)
#fopen Out sFilename write
#debug "\nCreating output file with union of boxes\n"
#local s = 0.4999999;
#write(Out, "union{\n")
#local Y = maxY;
#while (Y>0)
#debug concat("\n: ",str(Y,0,0)," ")
#local X = maxX;
#while(X>0)
#debug concat(str(X,0,0)," ")
#write (Out, "box{",
v2str(<X-s,-0.001,Y-s>),",",v2str(<X+s,world[X][Y],Y+s> )
#write (Out, " texture{") //Start texture
#if(mod(X+Y,2))//The texture
#write (Out, "tWhiteBox")
#else
#write (Out, "tBlackBox")
#end
#write (Out, "}}\n")//End texture and end box.
#local X = X - 1;
#end
#local Y = Y - 1;
#end
#write (Out, "scale ", v2str(<1/maxX,1,1/maxX>), "\n" )
#write (Out, "}\n")
#fclose Out
#end
And in the debug output, it goes from 200 : to 189 in Y, and when the 189 row is
finished, inside the 188'th, it crashes.
Is this something with a limited number of #write operations ???
If this isn't enough code, contact me and I can send the whole include file. (I
want to clean it a bit, and add comments before releasing it. as well as some
demos)
and here are the crash data.

Tested in linux, parses with ease.
So the error is in the windows version(or in windows)
