[Debug] Debug.* (Debug.Log, Debug.Format, Debug.LogError and etc.) crashes editor if inspected



(Check the attached *.gif file to see the bug)

Steps to reproduce:
1. Open the attached project
2. Navigate to Assets
3. Open the Introduction scene(Assets-> _App-> Introduction-> Scenes-> Introduction.unity)
4. Open the script (CentralizedSceneManager.cs) using Visual Studio 2015 (Assets-> _App-> Shared -> Scripts-> SceneLoader-> CentralizedSceneManager.cs)
4. Set breakpoint on line 26 and attach to Unity
5. Run Unity
6. Once breakpoint is reached, press F11 (Step into)
7. You will be on line 33 (Debug.LogFormat()). This line causes the issue.
8. Press F11 (Step into)
9. You will see that several lines of code were skipped (caused by Debug.LogFormat())
10. Repeat 'Step 8', till you will be on line 33 (again)
11. Unity crashes

Expected result: Debugging without problems
Actual result: Unity crashes without/with displaying error message or Visual Studio debugger skipping lines of code
