You are not supposed to access any members of struct ao2_iterator directly as documented where the struct is defined in astobj2.h:
{noformat}
/*!
 * \brief The astobj2 iterator
 *
 * \note You are not supposed to know the internals of an iterator!
 * We would like the iterator to be opaque, unfortunately
 * its size needs to be known if we want to store it around
 * without too much trouble.
 * Anyways...
 * The iterator has a pointer to the container, and a flags
 * field specifying various things e.g. whether the container
 * should be locked or not while navigating on it.
 * The iterator "points" to the current container node.
 *
 * Details are in the implementation of ao2_iterator_next()
 */
struct ao2_iterator
{noformat}

The violators are these functions:
handle_negotiated_sdp()
create_local_sdp()
