MySQL and C

This might be a C problem.
I'm using gcc(3.2) under Linux.
The compilation is OK but execution cause Segmentation fault.
The error was caused in the line:
temp_rate->point = atoi(row[1]); in function CheckRate()
Please help. TIA.

The source code are follow:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <mysql.h>

struct rate
{
char number[64];
char prefix[32];
int id;
int point;
int second;
int duration;
};

int main(int argc, char *argv[])
{

if (argc < 2)
{
exit(0);
}

struct rate current_rate;
strcpy(current_rate.number, argv[1]);
current_rate.id = 1;

MYSQL *conn;

conn = mysql_init(NULL);
if (conn == NULL)
{
fprintf(stderr, "mysql_init() failed (probably out of memory)\n");
exit(1);
}

if (mysql_options(conn, MYSQL_READ_DEFAULT_FILE, "./config.ini") != 0)
fprintf(stderr, "loding config file error\n");

if (mysql_real_connect(conn, NULL, NULL, NULL, NULL, 0, NULL, 0) == NULL)
{
fprintf(stderr, "mysql_real_connect() failed:\nError %u (%s)\n",
mysql_errno(conn), mysql_error(conn));
mysql_close(conn);
exit(1);
}

if (CheckRate(conn, &current_rate))
{
printf("Found\n");
printf("Code = %s,\tRate = %s,\tNumber = %s,\tSECS = %d,\tLIMITS = %d\n", cu
rrent_rate.prefix, current_rate.point, current_rate.number, current_rate.second,
current_rate.duration);
}
else
{
printf("Not Found\n");
}

mysql_close(conn);
exit(0);
}

int CheckRate(MYSQL *conn, struct rate *temp_rate)
{
MYSQL_RES *res_set;
int FOUND = 0;
char sql_cmd[128];
strcpy(temp_rate->prefix, "NOT FOUND");

sprintf(sql_cmd, "SELECT CODE, RATE, SECS, LIMITS FROM rate WHERE GID='%d' ORD
ER BY LENGTH(CODE) DESC", temp_rate->id);
//printf("%s\n", sql_cmd);
if (mysql_query(conn, sql_cmd) != 0)
{
fprintf(stderr, "query error\n");
}
else
{

res_set = mysql_store_result(conn);
}

MYSQL_ROW row;
while ((row = mysql_fetch_row(res_set)) != NULL)
{
if (strncmp(row[0], temp_rate->number, strlen(row[0])) == 0)
{
strcpy(temp_rate->prefix, row[0]);
temp_rate->point = atoi(row[1]);
temp_rate->second = atoi(row[2]);
temp_rate->duration = atoi(row[3]);

FOUND = 1;
break;
}
}

printf("Code = %s,\tRate = %s,\tNumber = %s,\tSECS = %d,\tLIMITS = %d\n", temp
_rate->prefix, temp_rate->point, temp_rate->number, temp_rate->second, temp_rate
->duration);
mysql_free_result(res_set);
return (FOUND);
}

Got it to work.
There're some hidden characters in the file. I re-typed the program again and everything is fine.
