You're going to have to debug it more deeply than that to tell anyone 
something useful.  At the very least, we need a backtrace.

Try this modified program instead:



#include <mysql++.h>
#include <iostream>

using namespace std;
using namespace mysqlpp;

int
main(int argc, char *argv[])
{
     try {
         Connection con(use_exceptions);
         con.connect("db", "localhost", "user, "pass");
         if (!con.connected()) {
             cout << "Can't connect!" << endl;
             return 1;
         }
         cout << "Closing connection.." << endl;
         con.close();
         cout << "Exiting.." << endl;
     }
     catch (exception& e) {
         cout << "Exception caught: " << e.what() << endl;
     }

     return 0;
}


Notice how it catches exceptions.  Your symptom could just be caused by 
an uncaught exception.
