I have been working on building finite-discrete element model to simulate fracture generation, and polyhedra elements in yade are used for DEM. 

After several steps, it seems that an infinite loop occurs when yade.O.step() is called. I want to trace back to the source of this bug, but it seems O.step() has called several functions in boost library, and it is hard for me to understand what codes in Yade are involved for O.step().

Could you please give me some advice on locating this bug? It will be very helpful if someone can tell my what codes in Yade are called for O.step().

By the way, the engine I used is as following:
O.engines = [
	ForceResetter(),
	InsertionSortCollider([Bo1_Polyhedra_Aabb()]),
	InteractionLoop(
		[Ig2_Polyhedra_Polyhedra_PolyhedraGeom()],
		[Ip2_PolyhedraMat_PolyhedraMat_PolyhedraPhys()],
		[PolyhedraVolumetricLaw()]
	),
	NewtonIntegrator(damping=0),
]
