rogue.hardware.axi.AxiStreamDma + rogue.protocols.packetizer.CoreV2 = seg fault

      Here's what the original code had (no segfault):

                      # Connect the SRPv3 to tDest = 0x0
                vc0Srp  = rogue.hardware.axi.AxiStreamDma(pcieDev,(pcieRssiLink*3)+0,1)
                srp = rogue.protocols.srp.SrpV3()                
                pr.streamConnectBiDir( srp, vc0Srp )

      If I add the packetizer, then I get the fault:

                      # Using PackVer2 after the DMA in firmware
                dma  = rogue.hardware.axi.AxiStreamDma(pcieDev,pcieRssiLink,1)
                pack = rogue.protocols.packetizer.CoreV2(False,False) # ibCRC = False, obCRC = False
                pr.streamConnectBiDir( pack.transport(), dma )

                # TDEST 0 routed to stream 0 (SRPv3)
                srp = rogue.protocols.srp.SrpV3()
                pr.streamConnectBiDir( srp, pack.application(0x0) )
