Subject: Cygwin seg faults using dyn. memory
To: cygwin AT cygwin DOT com
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii

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;
}
