[ntp:hackers] Crash from pool DNS lookup

I got one.  Anybody familiar with the code for this area?

My connection to the net and hence DNS was acting up about this time.  I 
suspect I hit a legal but very uncommon case.

 4 May 09:52:37 ntpd[30388]: 108.61.194.85 0011 81 mobilize assoc 18607
 4 May 09:52:37 ntpd[30388]: Soliciting pool server 74.123.28.4
 4 May 09:52:37 ntpd[30388]: 74.123.28.4 0011 81 mobilize assoc 18608
 4 May 09:52:37 ntpd[30388]: ../../libntp/work_thread.c:271: INSIST(((void 
*)0) != req) failed
 4 May 09:52:37 ntpd[30388]: exiting (due to assertion failure)

Line 271 is in receive_blocking_req_internal

        req = c->workitems[c->next_workeritem];
        INSIST(NULL != req);   <==
        c->workitems[c->next_workeritem] = NULL;

Where is the FAQ that tells me how to get a core dump?  (This is an old old 
Fedora system.)
