SCNParticleSystem subclass with custom property causes crash!

Classification:Crash Reproducible:Always
 
If I subclass `SCNParticleSystem` and add a property to the custom subclass, and assign a value to the property. `SceneKit` will crash on Mac. But it works on iOS and tvOS!

The crash always occurs when the particle systems emitter shape is being assigned a `SCNNode` geometry!
Its that: EXC_BAD_ACCESS (code=1...)

See the screenshots & test my simple example project.
Xcode 7.2, Xcode 7.3 beta (7D111g), Mac OS X 10.11.3 (15D21)
