mq->cont is only set in GST_neighbours_send And GST_neighbours_send is only used in: gnunet-service-transport_clients.c:clients_handle_send GST_neighbours_send (&obm->peer, obmm, msize, GNUNET_TIME_relative_ntoh (obm->timeout), &handle_send_transmit_continuation, stcc); gnunet-service-transport.c:transmit_our_hello GST_neighbours_send (target, (const char *) hello, ntohs (hello->size), GNUNET_CONSTANTS_HELLO_ADDRESS_EXPIRATION, NULL, NULL); |
|
|
Shutdown order in transport-service is: GST_neighbours_stop (); ... GST_clients_stop (); I can not explain this issue...this cannot happen :-) |
|
|
Well, an unfortunate range error could garble contents of the callback. Anyway, it might be an isolated incident. |
|
|
I hope so...I have no explanation why the address &handle_send_transmit_continuation should be corrupted |

Fixed in SVN 18696. |
