**Short description of error**
I am using that new feature in blender that combines GPU and CPU rendering but it quite crashing after a period of time in big scenes that require quite a time to render them and it really frustrating me that it crashes after like 2 hours of rendering and not continue, on the other hand when I use GPU or CPU render as regularly it works fine but much bigger time to render.
**Exact steps for others to reproduce the error**
1- enable gpu and cpu rendering
2- click render on an intense scene
3- wait for it!!
[Based on the default startup or an attached .blend file (as simple as possible)]
