If AmbiguousMatchException happens, unity editor(Windows) ruined.

Could you check this weird phenomenon?
This bug lives on Unity 5.5.

If AmbiguousMatchException happens, unity becomes lame.
Catched or not, your unity are infected.

After playmode ends, editor will be freezed in some machine.
In some machine, editor works normally. But if you check cpu usage, editor will be spending 25~30%.

Test below code.

Code (CSharp):

1. using System;
2. using UnityEngine;
3.  
4. public class TestClass {
5.     public void Overloaded(string b) { }
6.     public void Overloaded(int a) { }
7. }
8.  
9. public class BugBehaviour : MonoBehaviour {
10.     void Start () {
11.         try {
12.             var methodInfo = typeof(TestClass).GetMethod("Overloaded");
13.         }
14.         catch( Exception e ) {
15.             Debug.LogException(e);
16.         }
17.         Debug.Log("Exception catched. But your unity already infected.");
18.     }
19. }
20.
