4.3 Editor Crash - Changing Script

Assuming the following two scripts;

Code (csharp):

1.  
2. public class WithoutGUI : MonoBehaviour { }
3.  

and

Code (csharp):

1.  
2. public class WithGUI : MonoBehaviour
3. {
4.     private void OnDrawGizmos()
5.     {
6.         Gizmos.DrawSphere(Vector3.zero, 10f);
7.     }
8. }
9.  

Switching the script applied to a GameObject from one to the other using the "Script" field makes the Editor crash 100% of the time with the following callstack;

41. ========== END OF STACKTRACE ===========
42.  

The crash only occurs when switching from a script that has OnDrawGizmos to a script that is lacking that method.

 

Here you go, I submitted an empty project from that crash report that only has those 2 scripts.

A few extra precision;

1) Apply the WithGUI script to any empty object. I didn't add it to the Camera, and it shouldn't change anything.
2) Be sure the item being drawn on the OnDrawGizmos() - the sphere or whatever - is visible on screen (SceneView).
3) Change the script, I use the Object Picker dialog to change the script to the WithoutGUI one. I also tried it by dragging the script on the field, same crash.
4) Crash!

 

I also see this behavior. I must hide the Scene view, then replace the script, then save the prefab/scene, and then restart Unity. If I don't restart, then the next time I show the Scene it will crash.
