ROOT system not initialized???

I'm trying to run a simple test program to understand using TOrdCollection
and TOrdCollectionIter and having a problem. When I run the code, it gets
to main's closing brace and gives me an endless stream of:

Fatal in <TClass::TClass>: ROOT system not initialized
aborting
Fatal in <TClass::TClass>: ROOT system not initialized
aborting
....

The code is:

#include <iostream.h>
#include "TROOT.h"
#include "TOrdCollection.h"
#include "TH1.h"

int main()
{
TROOT root("name","title");

TOrdCollection * coll = new TOrdCollection(3);

TH1D* h1 = new TH1D("name1","title1",100,0.0,500.0);
TH1D* h2 = new TH1D("name2","title2",100,0.0,500.0);

coll->AddLast(h1);
coll->AddLast(h2);

TOrdCollectionIter iter(coll);

cout<<((TNamed*)iter.Next())->GetName()<<endl;
cout<<((TNamed*)iter.Next())->GetName()<<endl;

if (iter.Next() == 0) cout << "yes" << endl;

return 0;
}

If I comment out the three lines with cout in them, I don't get any
errors. This is all on Windows NT under MS VC++ 6.0. If I compile and
run on Unix (SGI), I don't get any problems either way. Am I missing
something?
