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;
    }
