Ahh. of course..... Thanks Simon.

That created most of the files, and then died:

Program received signal SIGSEGV, Segmentation fault.

) at nsd-patch.c:354

        configfile = 0xbfddcb92 "/etc/nsd/nsd.conf"
        difffile = 0x1 <Address 0x1 out of bounds>
        options = (nsd_options_t *) 0x14
        db = <value optimized out>
        zone = (struct zone *) 0x81161c4
        commit_log = (struct diff_log *) 0x81d96d4
        debug_list_diff = 0
        force_write = 0

The diff file was specified via the nsdc patch command as "-x /var/lib/nsd/ixfr.db"
and is available there:
-rw-r--r-- 1 nsd nsd 607249 Nov  7 19:30 /var/lib/nsd/ixfr.db

But the pointer to the difffile seems to have gotten corrupted.

Is there anything else I can supply to assist debugging this?
