The below code is some code being written by Xaviar Czervik. It isn't even partially done, and if I were a programmer it'd be version 0.00.0.000.0.01, although I don't do that... So, if you're interested in crashing the LSL compiler (This code doesn't compile 99% of the time) check out the code below. And in case you couldn't tell, I don't believe in comments.
