Need help with Unity Editor crashing

How can I avoid this crash in the Unity Editor? It appears to be crashing in a hashing algorithm. Seems to be triggered by instantiating rigidbodies and particles.

Code (CSharp):

The editor should never crash, thus you can consider it a bug.

Please submit a bug-report as described in this document:
https://unity3d.com/unity/qa/bug-reporting

After you submitted the bug-report, you receive a confirmation email with a Case number. Please post the Case number here for Unity staff to pick up.

 

Unfortunately the Unity QA team will no longer accept bug reports for Unity 5. I doubt that such an obscure crash was fixed, but go figure.

 

In this case, any reason why you don't upgrade to 2017.4 LTS?

 

Switching engine versions isn't really practical under our current schedule right now.
