What is surprising is that all the columns are not zero!  The original poster
was offering some speculations as to how that might have happened, but as you
say (and I think he'd agree) it doesn't wash.  I ran his posted code and
got all zeroes.  Either there's a *serious* problem with his compiler, or the
posted code is not the same as what he compiled.  Either way, he should try
to pin down the cause of the trouble with more print statements, etc...
