Reproduction steps:
1. Open the attached project;
2. Open the scene "game";
3. Enter Play mode;
4. Pass the logo screen and start clicking on the bushes;

Actual result: Unity crashes at <Coroutine::CompareCoroutineEnumerator>.
Expected result: Unity should not crash.

Note: The crash is related with GameMaster.cs, IEnumerator UpdateLoop_IntroAndPlayMusicAfterwards function. When you comment it, everything works fine.
The crash maybe related with the fix of case 852360 because it started crash from 5.6.0b9 version.

Reproduced with: 5.6.0b9, 5.6.0b11, 2017.0a2
Not reproducible with 5.6.0b6, 5.6.0b8
Regression introduced in 5.6.0b9

Can not test with the older version than 5.6.0b6 because there are compiler errors.
