I compiled using this patch and without --disable-atomic, unfortunately
named refused to start:
10-Oct-2006 19:28:22.894 general: rbtdb.c:1128: INSIST(((unsigned
int)((&rbtdb->node_locks[node->locknum].references)->ref
s))) failed
10-Oct-2006 19:28:22.894 general: exiting (due to assertion failure)
Thanks for your help, kind regards
