After freeing the data structures we have to reset the counters to zero. This fixes a segmentation fault when virNetDevIPInfoClear is called twice (e.g. this is possible in virDomainNetDefParseXML() if virDomainNetIPInfoParseXML(...) fails with ret < 0 (this leads to the first call of 'virNetDevIPInfoClear(&def->guestIP)') and the resulting call of virDomainNetDefFree(def) in the error path of virDomainNetDefParseXML() (this leads to the second call of virNetDevIPInfoClear(&def->guestIP), and finally to the segmentation fault).
