Unity 5 RC1 and il2cpp build

Hey guys!

Can you find a solution for solve this bug? I mean A*PathFinding in 64bit iOS (with il2cpp),
I try ASTAR_NO_ZIP and I resolve exception with Pathfinding.Ionic.Zip.Reduced this OK
But next I got exception: No metadata found in serialized data. I repeat it happens on iOS with il2cpp !

How can fix this?
Thanks
