Whenever I look either left or right in the game, it crashes.

I thought that I was able to turn around, but what really happened was the game crashed.

Steps to Reproduce:
1. Start Minecraft snapshot 14w30c.
2. Enable "Use VBO's" in Options>Video Settings.
3. Open any world in Singleplayer.
4. After the game has loaded, look left or right to crash the game. The launcher will see Minecraft has closed, but will not recognize this as a crash.

Also: looking up or down will not crash the game.
