Are Compute shaders not compiling in Unity 5 b20?

I have two compute shaders that aren’t compiling in Unity 5, where they were compiling without errors in 4.5. Was there a change to how they are compiled? I don’t get any debug information back other than the following:

Shader error in ‘compute shader.compute’: Compute shader compilation had a problem, your compute shader was not compiled correctly

Here is a project that has the same issue I am having:

Please submit a bug, there’s a menu item Help->Report a Bug in Unity Editor, and attach a project.

Thanks

I’ve had problems with this too throughout beta 5. I haven’t gotten around to putting together something to submit yet though.
