1) Open attached project
2) Click on particle system in the hierarchy
3) Observe the particle system simulate nicely
4) Now set the Gravity Modifier setting to 1 divided by 0 (Unity defaults this to Infinity)
5) Observe the console spam errors when simulating the particle system. This is the bug.

Expected result: the gravity modifier should handle invalid data with a more informative error that leads users to fixing the problem. i.e. "Invalid Gravity Modifier value on particle system <particle system name>."
