Cygwin seg faults using dyn. memory

cygwin seg faults when i attempt to assign values to
allocated dynamic memory. The same code isn't
seg-faulting on a Compaq Tru64 UNIX V5.1A machine.
is there a setting where the heap needs to be
adjusted? are there libraries i need to include that
i haven't?
here's the embarassingly simple problematic code:
#include "Name.h"
#include "readItem.h"
#include <iostream.h>
#include <string.h>
using namespace std;
int main() {
Name * dummy2;
dummy2 = new Name;
cin >> dummy2;
cin >> *dummy2;
cout << *dummy2;
return 0;
}
