    My issue was wrongfully closed as duplicate, and differs as follows:

    Steps to reproduce:

    - Create a NEW Unity Project (3D)
    - Add "Standard Assets -> Particles"
    - Create a "Particle System"
    - Add Sub-Emitter (+)
    - "Out of memory" crash after 1-5 seconds (on a 32GB system)
