occi分段错误错误

Question

我使用OCCI连接Oracle和C ++。当我尝试访问表中的所有记录（有10条记录）时，以下代码片段仅显示表中的4条记录，程序以“分段错误”消息结束。

表员工

Name         Null?    Type
 ------------ -------- ---------------
 ID           NOT NULL NUMBER(6)
 NAME         NOT NULL VARCHAR2(30)
 AGE          NOT NULL NUMBER(3)
 SALARY       NOT NULL NUMBER(6)
 VA                    NUMBER(8,2)

代码

    #include<occi.h>
#include<stdio.h>
#include<iostream>
using namespace oracle::occi;
using namespace std;


int main ()
{
   Environment *env;
   Connection *conn;
   string userName ;
   string password ;
   string database ;

   userName="e224312";
   password="ipgdMCicy";
   database="oraconn";

   cout << "OCCI Demo" << endl;

   env=Environment::createEnvironment(Environment::DEFAULT);
   conn=env->createConnection(userName,password,database);

   cout << "OCCI Environment  and Connection Created " << endl;

   int idx=0;
   int ch;
   int c1;
   string c2;

   int c3;  

   Statement *stmt = conn->createStatement("SELECT * FROM employee");
   cout << "Selecting Records from Table " << endl;
   ResultSet *rs = stmt->executeQuery();

   while(rs->next()){
    c1 = rs->getInt(1);
    c2 = rs->getString(2);
    c3 = rs->getInt(3); 
    cout <<"ID   :" << c1 << endl;
    cout <<"Name :" << c2 << endl;
    cout <<"Age  :" << c3 << endl;
   }
   cout << "Terminating the Connection and The Environment" << endl;
   env->terminateConnection(conn);
   Environment::terminateEnvironment(env);

   cout << "Normal End" << endl;
}

我正在使用unix g ++编译器。这种突然结束执行的原因是什么，我该如何纠正呢？

这是g ++编译器的问题。当我使用gcc编译器时它工作。
