Description:
------------
I'm trying to bind the parameters for a SELECT query using the mysqli extension. So, I prepare the query, bind the variables, execute, an obtain the result. But in the obtained result I can fetch row (the correct quantity), I can fetch the fields, but it doesn't return any data....

Reproduce code:
---------------
$handle = new mysqli('x.x.x.x', 'x', 'x', 'x');
$stmt = $handle->prepare('SELECT User.User FROM User WHERE User.User = ? AND User.Password = ?');
$user = 'plenque';
$pass = 'plenque';
$stmt->bind_param('ss', $user, $pass);
$stmt->execute();
$result = $handle->store_result();
echo '<pre>';
var_dump($result->fetch_fields());
var_dump($result->fetch_assoc());
echo '<pre>';
$result->close();
$stmt->close();
$handle->close();

Expected result:
----------------
array(1) {
  [0]=>
  object(stdClass)#4 (9) {
    ["name"]=>
    string(7) "User"
    ["orgname"]=>
    string(7) "User"
    ["table"]=>
    string(7) "User"
    ["orgtable"]=>
    string(7) "User"
    ["def"]=>
    string(0) ""
    ["max_length"]=>
    int(0)
    ["flags"]=>
    int(1)
    ["type"]=>
    int(253)
    ["decimals"]=>
    int(0)
  }
}
array(1) {
  ["User"]=>
  string(0) "plenque"
}

Actual result:
--------------
array(1) {
  [0]=>
  object(stdClass)#4 (9) {
    ["name"]=>
    string(7) "User"
    ["orgname"]=>
    string(7) "User"
    ["table"]=>
    string(7) "User"
    ["orgtable"]=>
    string(7) "User"
    ["def"]=>
    string(0) ""
    ["max_length"]=>
    int(0)
    ["flags"]=>
    int(1)
    ["type"]=>
    int(253)
    ["decimals"]=>
    int(0)
  }
}
array(1) {
  ["User"]=>
  string(0) ""   <----- ?????????
}
