[Richard Jones]

  David,

Yes, that fixed it.  Thanks for fixing this so quickly.  Jake, you should be good to go with testing production on the cluster now.

Wonder is, the other 1/3 of the time the command succeeds ok.  If you build the above with DEBUG=1 and run mcsmear_d instead of mcsmear, it never seg faults.  Weird.  Any ideas?
