9         Setting                            Description
10                          Overwrite memory with tag values when allocating
11-DISC_MEM_DEFAULTFILL=1   or freeing it; this impairs performance but
12                          makes debugging of memory problems easier.
13                          Don't track memory allocations by file and line
14-DISC_MEM_TRACKLINES=0    number; this improves performance but makes
15                          debugging more difficult.
16-DISC_FACILITY=LOG_LOCAL0 Change the default syslog facility for named
17-DNS_CLIENT_DROPPORT=0    Disable dropping queries from particular
18                          well-known ports:
19-DCHECK_SIBLING=0         Don't check sibling glue in named-checkzone
20-DCHECK_LOCAL=0           Don't check out-of-zone addresses in
21                          named-checkzone
22-DNS_RUN_PID_DIR=0        Create default PID files in ${localstatedir}/run
23                          rather than ${localstatedir}/run/named/
24                          Disable the use of inline functions to implement
25-DISC_BUFFER_USEINLINE=0  the isc_buffer API: this reduces performance but
26                          may be useful when debugging
27-DISC_HEAP_CHECK          Test heap consistency after every heap
28                          operation; used when debugging
