Heh. I wasn't the one who originally did that, but I remember screwing around with stuff like that too just to see what would happen when I saw people posting about it. I know I got into the millions and crashed it when it couldn't allocate enough memory for all the ships. If no one's "fixed" it since I last tried, Defender mode is excellent for hard-crashing the game that way even now after the addition of carriers and whatnot. You can pretty easily get into seven digits with the right settings/starting condition, and then it explodes.
