Cycles Volumetrics bug causes PC Freeze/Crash

Blender Version

Short description of error
When I try to render (in cycles) with a Volumetric Shader attached to a Cube and its hidden in Outliner, I get a System crash, even to this state, that i had to repair Windows (after 6 crashes till I found the cause)! I also get a PC crash, if I try to disconnect the volume scatter node, while in rendered view. When the volumetrics Object is visible, then it seems stable and renders fine.
I'm Pretty sure this is a AMD Driver / GPU related Problem, because when I render with the cpu, it works fine…
Apart from that, my system is rockstable and I had no crashes or bluescreens since I Bought it (6 months old)

Exact steps for others to reproduce the error
Open the atached file and go in the rendered view. But I think ist AMD/ Radeon GPU related so everyone with a nvidia GPU should have no Problems at all.
