Ok, I traced it down to ./src/nm-device-olpc-mesh.c:is_companion(), at the memcmp() line. their_addr is on the stack, so the invalid pointer must be priv. I can't debub further without rebuilding the rpm with -g. Any idea what might have gone wrong here? static gboolean is_companion (NMDeviceOlpcMesh *self, NMDevice *other) { NMDeviceOlpcMeshPrivate *priv = NM_DEVICE_OLPC_MESH_GET_PRIVATE (self); struct ether_addr their_addr; if (!NM_IS_DEVICE_WIFI (other)) return FALSE; nm_device_wifi_get_address (NM_DEVICE_WIFI (other), &their_addr); if (memcmp (priv->hw_addr.ether_addr_octet, their_addr.ether_addr_octet, ETH_ALEN) != 0) { return FALSE; } -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
