System Information
Operating system: Windows 10
Graphics card: GTX 980 Ti

Blender Version
Broken: 2.80, 9315cc443b1d-win64, blender2.8, 2018-02-20
Works: 2.79

Open Blender with any file. Create an extra Scene. Select the other scene as a "Background Scene" in the Scene tab. Blender crashes.

This happens on all my files with 2.8 and has done so for awhile. 2.79 works fine.

I can't reproduce this on my end with the default cube scene.

Should you provide the exact steps and perhaps a .blend file that demonstrates the issue.

IE:

Open the attached .blend file
Set background scene
crash.

Ah, I made a mistake. I thought it was the default startup scene, but it was pulling an old one from my %userdata% folder. It works fine again now with a completely fresh installation.

I'll attach the file here in case is still is of interest: startup.blend

Thanks for checking.

I can reproduce the crash with that file.

@Sergey seems like something funky is going on with the viewlayers?
