Win7 X64 with RX 480 or RX VEGA and 17.8.2 driver
Short description of error
Blender crashes when compiling the kernel when a blackbody node is added and not even connected
Exact steps for others to reproduce the error
Open attached file and hit F12
By the way, why an unconnected node that is removed by the tree cleaning operation triggers a group level of 3? Doing the cleaning (including unfolding) first would prevent using a suboptimal kernel would diminish the number of kernel recompiling.
