Crash when a particle system is sub emitter of more than one other particle system



I'm hitting a crash any time I assign one particle system to be a sub emitter of more than one other system. I'm also seeing these warnings pop out when I do this which could be related:

Assertion failed on expression: 'count >= toIndex'
(Filename: C:/buildslave/unity/build/Runtime/ParticleSystem/ParticleSystem.cpp Line: 2853)

Assertion failed on expression: 'particles.array_size() == count'
(Filename: C:/buildslave/unity/build/Runtime/ParticleSystem/ParticleSystem.cpp Line: 2854)

I tried to repro this in 5.5 and it does not occur there. Reproduced in editor play mode as well as windows standalone.

Create 3 particle systems
in the sub-emitter of two of them assign the 3rd one to both
run (only seems to happen just after running, if you enable this during run no crash occurs)
