Broken: version: 2.80 (sub 71), branch: master, commit date: 2019-05-20 16:16, hash: 9efe117535

Short description of error
Instant crash when pressing Bake Indirect Lighting with a specific shader node.

Exact steps for others to reproduce the error
BakeIndirect.blend
Press Bake Indirect Lighting

The crash will not happen if the PrincipledBSDF shader is deleted or even replaced with a fresh Principled BSDF node!
