Short description of error
Assert in Hair BVH code trying to render the 2.80 splash image.
Exact steps for others to reproduce the error
This is on a WIndows 10 system with 16GB of RAM, CPU rendering as setup in the .blend. I thought it was some sort of memory exhaustion that was causing Blender to silently exit about 20% through the rendering process as that happened every time I tried to render it. So I did a debug build and after an hour or so I got an assert (details below).
To try to reproduce, just get the splash image .blend from https://cloud.blender.org/p/gallery/5d2607ee6b3001d49bab798a open it and hit F12. For me the RC equivalent version here quits silently at ~20%-30% of the way through the render.
I don't know if the failure point is deterministic as I've only had time to run the debug build once. @Harley tried the same thing and got a failure after a similar time but wasn't able to get information out of his debugger.
The debug build hits the assert at ob_traversal.h:249:
Here's the stack trace out of VS Code:

I was able to render on GPU, on a CPU it did crash.

I tested that scene file on my laptop and it renders fine. The memory consumption is about 20GB of RAM and 10GB of VRAM during the scene's rendering with tiles at 64x64, on a Windows 10 Pro 64bit OS, with Nvidia GeForce GTX 1070 (8GB VRAM), and Blender 2.80 (Hash:
