I call a method from an AnimationClip event. If I call Animator.Update from inside that method the Animator will re-trigger the event, resulting in a endlessly recusive call and stack overflow. This occurs even if attempting to change the Animator state.

Steps to reproduce:
1. Open attached project's scene "Main".
2. Enter play mode.
3. Select Canvas/"Animation Root" game object.
4. Press "Hide: button under "Animated Object" script
5. Unity gets stuck.

Reproduced with 5.2.0f3, 5.4.0b12.
Does not reproduce on 5.1.4f1 and earlier
