  As a newcomer let me introduce myself, Kevin Hannan.  I hope to be of some
help here.  Soon I will have hardware in place to begin helping.  In the
meantime I'll mainly try to catch up and help when possible.

  For my 2 cents on this... It appears to be an offset into a structure with
either 2 pointers or longs, or some other mixture + alignment to equal 8 bytes.
All this occurring in dn_send_disc near the end of the function (close to
dn_nsp_disc_init).  Also, ck_free and sock_wfree are next up the stack.
  This is just a guess, but I hope it gives some insight/assistance.
