--- Comment #3 from Robert <rhollida at ciena dot com> ---
This is my suggested fix for this issue:

Use the size pointer *thisanssizp, instead of *thisansp, when creating the new
buffer.

u_char *newp = malloc (MAXPACKET);
                        if (newp != NULL) {
                                <*anssizp = MAXPACKET;>     :REMOVED LINE:
                                *thisanssizp = MAXPACKET;   :ADDED LINE:
                                *thisansp = ans = newp;
                                if (thisansp == ansp2)
                                  *ansp2_malloced = 1;
