#221: Segmentation Fault on schedule.c:232

    Type:  defect                                    |      Status:  new     
Priority:  trivial                                   |   Component:  Signer

 When running OpenDNSSEC 1.3.0-trunk (r4624), I got a SEGFAULT.
 The problem is here:
     del_node = ldns_rbtree_delete(schedule->tasks, (const void*) task);
     if (del_node) {
         del_task = (task_type*) del_node->data;
     } else {
     if (del_task->flush) {

 If for some reason del_node returns NULL, del_task will be NULL as well,
 so del_task->flush will cause a SIGFAULT (which is my case). I saw the
 warning before ods-signerd crashed and I have the core dump as well. A
 workaround is to change the condition to
    if (del_task && del_task->flush)
 but I'm not sure if it breaks your logic.
