There has been a regression in the AMD GLSL compiler that appears to affect the gl_FrontFacing builtin in certain cases. I'm investigating this at the moment. You can rename a couple of shaders in the $HH/ogl2 directory in your Houdini distribution, or you can revert the Catalyst driver to 10.9.
To do the ogl2 rename patch, go to the <Houdini-install-path>/Houdini/ogl2. Rename ogl2_face_forward.func to ogl2_face_forward.bak, then ogl2_face_forward_osx.func to ogl2_face_forward.func (essentially making a backup of the shader causing the problem and replacing it with a shader that has an approximation of gl_FrontFace). This problem popped up on OSX for a time last year, so that alternate shader is the workaround for it.
