Add the following code to the Start method of any script attached to a gameobject in your current active scene and press Play. Unity crashes!

ParticleRenderer p = gameObject.AddComponent<ParticleRenderer>();
p.uvAnimationXTile = int.MaxValue;
p.uvAnimationYTile = int.MaxValue;

Calling this code froze Unity and my MacBookPro in a way where I couldn't even force quit out of it and the laptop got so hot I thought it would literally melt.

Maybe those two values should be capped to some sensible values.
