This outcome seems equally likely, if not more so. However, if we assume that we are (or at least, if I assume that I am) living in a computer simulation, and we/I decide that crashing it is a desirable outcome, the first step is to consider the nature of the simulation. Is the computer computing every wave-function of every particle in the universe once every Planck time? Is it more like the Matrix, where the computer simulation runs at the level of everyday objects and people, so that people and animals could be controlled by AIs, and a desk is represented as a desk, and not a bunch of atoms? Is the computer really simulating the rest of the universe at all, or are the stars and galaxies just painted on the wall, and appear indistinguishable from actual stars and galaxies, complete with simulations of redshift and all the rest built right in?
The answer to these questions determine the likely points of attack for crashing the simulation, with the possibilities getting easier and more accessible as the computer takes more and more shortcuts to avoid simulating every particle in the universe. For example, if the computer is, in fact, simulating everything down to the last detail, then crashing it would seem stupendously difficult, since the results of practically any action we could take are determined by laws that have been running quite handily since at least the Big Bang, and have likely seen quite a lot of stress testing during that time. The only way to expose bugs that haven't popped up before is to create conditions that have not occurred before, likely involving energies much higher than those experienced in the Big Bang. So building a particle accelerator powered by a dyson sphere around a supernova seems like a plausible plan, if anything were going to work at all. But I wouldn't count on it.
However, if the computer simulation really only cares about us, they might well have decided to throw away the 99.999...% of the universe we'll probably never get to visit, and are just simulating our solar system. In this scenario, only our solar system really exists, and the rest of the universe is just smoke and mirrors. If this is so, perhaps all we need to do to crash the computer is send a probe (or actually travel) to another star. Or another galaxy, depending on how far the author of the simulation thought we'd get. This assumes, of course, that the simulation doesn't expand whenever we visit new places, which is a distinct possibility.
Things get even more interesting when we consider that the computer might not be simulating quantum physics at all, but is simulating objects at the human scale, and only fudging the results of all our quantum physics experiments, or something like that. If this is so, the only limit for how to crash the universe is your imagination. Maybe by capturing Agent Smith and brainwashing him we could cause a segmentation fault in his AI, which brings down the computer. Perhaps if we exactly collide 3 bullets in mid-air all at once we'll break the assumption in the Bullet.Collide() method that only two bullets would ever hit each other simultaneously, causing the program to complain about an incorrect number of arguments, and die. Maybe by committing genocide on a vast scale, I could tease out a bug that makes the program crash when numHumans <= 1. The possibilities are endless. Who could possibly know where to begin?
