'set()' causing a index out of bounds error?

benvancitters

I have a very simple processing sketch that is throwing a strange exception. I am running a windows 7 machine with Processing 2.2.1

PImage img; 

void setup() {
  size(500, 500, P3D);
  img = createImage(500, 500, RGB); 
  img.set(10,10, color(255,0,0));
}

void draw() {
  image(img,0,0);
}

throws this:

Strangley, if I change the line

img.set(10,10, color(255,0,0));

to include a for loop such as

  for (int i = 0; i < img.width*img.height; i++)
    img.set(int(random(img.width)),int(random(img.height)), color(255,0,0));

or

for (int i = 0; i < img.width*img.height; i++)
  img.set(i%img.width,i/img.width, color(255,0,0));

I don't get an exception. If I remove the for-loop the exception comes back!

Any ideas about what is going on here?!?

No exception @ Processing 2.0.2 here! :-?

I can reproduce a similar error (less detailed stack trace) in 2.1.1.

Why do you use the P3D mode in an apparently flat sketch?
