Hi, I just ran into the same problem on 5.2.0f3.
Editor and application crashed on destroying several gameObjects.
Reading your comments I was able to fix it by adding two simple things. <3
Basically i get the component Animator of the gameObject and disable it. (.enabled = false;)
Then I added a 0.1f timer to the Destroy function, and it works.
Hope this can help!

This is still happening with 5.1.2f1 it even crashes the Editor, not just on mobile!

As the original bug submitter, I can say that version 5.1.1p3 (and I believe as early as 5.1.1p1) is working for us. This includes the sample project I sent to Unity to replicate the crash. If anyone here is still triggering this problem with those versions of Unity, you will likely need to submit a new sample project that triggers the issue.

My comment that it would've been fixed in 5.0.2p1 was in the forum thread and based on the fact that I couldn't reproduce it in my specific case. There was no mention about this in the change log so I guess it was just luck on my side.

We were able to reproduce it in our case also in 5.1.0 so it means it is NOT fixed yet.

I don't think this was fixed in 5.0.2p1. The bug would be marked as "Fixed" and not active if that was the case.

Here are the reported fixes from 5.0.2p1 (notice that 694004 is not in the list)

Please ignore my comment. My issue was caused by an infinite loop happening very irregularly and showed the same symptoms as described here.

It's also present in 5.1.0f2.

It was reported as fixed in 5.0.2p1.
5.1 fix will come with 5.1 patch release 1.

The same issue occurs in 5.1.0f2 when I try to open a different scene.
