    iax2 frame double free
    
    The iax frame's retrans sched id was written over right
    before iax2_frame_free was called.  In iax2_frame_free that
    retrans id is used to delete the sched item.  By writing over
    the retrans field before the sched item could be deleted, it was
    possible for a retransmit to occur on a freed frame.
