Worked: (optional)

Short description of error
Unmuted and unconnected to the material output Subsurface Scattering makes the material not working. It looks like viewport isn't updated in the area of this material.
Here is the video with the error:
2019-07-25_09-42-48.mp4
And here is the blend file:
SSS bug.blend

Exact steps for others to reproduce the error

Open the attached file
Go to render preview mode.
Move around the viewport to notice the material not working on the cube
Mute or delete the SSS node and reconnect the Diffuse node to see that it is working now.

Can confirm this, the unconnected SSS node breaks every other shader, only exception seems to be Principled BSDF @fclem

I'm having the same problems with the unconnected Subsurface Scattering node in Eevee.

An unconnected Subsurfacescatter(SSS) shader will fully break the shader. Muting the unconnected SSS shader doesn't help.
You can mute a connected SSS shader and it doesn't break.
Just being thorough

Principled Shader still works.

I'm having this error, too. Principled is still working, probably because of this: f962c701fe

Here's an error in the console, not sure if it's related or not:

0(10042) : error C0000: syntax error, unexpected ',', expecting "::" at token ","```

Still happens in the latest 2.81 alpha. 4ce3fbd52a
