System Information
Operating system: MacOs 10.13.2, Ubuntu 16.04
Graphics card: Ubuntu with GTX 1050Ti

Blender Version
Broken: blender 2.80 e57ee5934a
Worked: blender 2.79 0260d7b726

Short description of error
Blender 2.80 crashes while trying to render any objects having this material shader.testCrash.blend

Exact steps for others to reproduce the error
Run blend file attached.

Any node or link removal will make the shader work. I could not simplify the shader more to make Blender crash.
Node input values do not have any impact to the exception of Subsurface of any of the bottom three Principled BSDF nodes. Subsurface input of at least one of them must be above 0.847 to make it crash.

Can confirm crash in current buildbot (7c438e536), cant get it to crash in a Debug build though (both 7c438e536 and 72b9ab5a22)...

(note: file also crashes on open in current buildbot for me -- if I open in a Debug build, change GPU to CPU, save again then it opens fine in buildbot [but crashes on render then...])

Not sure whats going on here, maybe @brecht can take a look?
