Rpc - 分段故障（核心转储）

Question

我尝试用ubuntu中的RPC编程一个新程序，服务器执行正常但我总是得到错误：执行客户端之后的分段错误（Core dumped）这是我的代码

banque.x

const max_cin = 8;

typedef string typeCin<max_cin>;

struct client {
     typeCin cin; 
     float solde;
};

typedef struct client client;

struct cnMysql{
     char * host;
     char * user;
     char * pass;
};
typedef struct cnMysql cnMysql;


program BANQUE {
  version Client {
     string Connect(cnMysql cn) = 0;
     string AddC(client c) = 1;
     client ConC(typeCin cin) = 2;
     string AddS(client c) = 3;
 }=0;
}=20162016;

banque_server.c

char **
connect_0_svc(cnMysql *argp, struct svc_req *rqstp)
{
    static char * result;

    result = "test";

    return &result;
}

banque_client.c

   // declaration 
        CLIENT *clnt;
        char * *result_1;
        cnMysql  connect_0_arg;
        char * *result_2;
        client  addc_0_arg;
        client  *result_3;
        typeCin  conc_0_arg;
        char * *result_4;
        client  adds_0_arg;
    //end declaration 
    //main
    connect_0_arg.host = "localhost";
    connect_0_arg.user = "root";
    connect_0_arg.pass = "root";

    result_1 = connect_0(&connect_0_arg, clnt);
