I got a problem regarding simple MySQL function which is mysql_fetch_row when ever I use it, my application will crash with it will go to the point when its executing. No matter what query I would run it will crash. The core dump says following:

(gdb) bt full
#0  0x2866397f in mysql_store_result () from /usr/home/ld/application
#1  0x28637905 in main () from /usr/home/ld/application
#2  0x08441d3a in CRC_GetCodeSize20 ()

The code looks simple:

int main()
{
  MYSQL *conn;      // the connection
  MYSQL_RES *res;   // the results
  MYSQL_ROW row;    // the results row (line by line)
 
  struct connection_details mysqlD;
  mysqlD.server = "localhost";  // where the mysql database is
  mysqlD.user = "mysqlusername";        // the root user of mysql   
  mysqlD.password = "mysqlpassword"; // the password of the root user in mysql
  mysqlD.database = "mysql";    // the databse to pick
 
  conn = mysql_connection_setup(mysqlD);
 
  res = mysql_perform_query(conn, "select 1, 2");
 
  printf("Result:\n");
  while ((row = mysql_fetch_row(res)) !=NULL)
      printf("%s\n", row[0]);
 
  mysql_free_result(res);
  mysql_close(conn);
 
  return 0;
}

What is the problem?

mysql_perform_query:

MYSQL_RES* mysql_perform_query(MYSQL *connection, char *sql_query)
{
   if (mysql_query(connection, sql_query))
   {
      printf("MySQL query error : %s\n", mysql_error(connection));
      exit(1);
   }
 
   return mysql_use_result(connection);
}
