This is listed as fixed, but I just confirmed it still happens in 2017.2.0f3. Grofie's and Zarlang's fix worked for me as a hack.

The patch release (2017.2.0p1) does not work for me.
But Zarlang's 'fix' helps. (Thx allot!)
I end up using this in my world particle manager, so I only have to call it once:
void Start ()
{
Debug.LogWarning("Preventing UNITY CRASH 957427: https://issuetracker.unity3d.com/issues/unity-crashes-when-particles-are-awaken-by-script");
foreach (ParticleSystem l_ParticleSystem in m_ParticleSystems)
{
l_ParticleSystem.Emit(1);
l_ParticleSystem.Clear();
}
}

If you manage to fix this crash using this:
- Call Emit(1)
- Call Clear
you still end up with a performance spike due to the Size Over Lifetime module

I found this issue as well. Will try the patch release.
