Question #190529 on Yade changed:
https://answers.launchpad.net/yade/+question/190529

Christian Jakob posted a new comment:
I found out, that fusionDetection=True is running, when no particle is
deleted. If particles are deleted, e.g. using updSph()

def updSph(rad=1.0):
	i = 0
	for ii in sphID:
		tempID = O.bodies.append(utils.sphere([O.bodies[ii].state.pos[0],O.bodies[ii].state.pos[1],O.bodies[ii].state.pos[2]], material=O.bodies[ii].material.id, radius=O.bodies[ii].shape.radius*rad))
		sphID[i] = tempID
		O.bodies.erase(ii)
		i+=1

, then there is a segmentation fault:
