Short description of error
When two different scenes with different percentage scales are composited together, blender crashes.

Exact steps for others to reproduce the error

Open blender
Create new scene (through full copy)(Referred to as Scene B)
Go back to the first scene (Scene A)
Go to the compositor and enable nodes
Duplicate Render Layers node, change linked scene to Scene B
Change Scene A render scale percentage in the output tab
Hit F12
