Oh, I swapped actual and expected results by mistake

Description:
------------
Probably I miss some point here but anyway - in the test script below bind data is passed to the
query() function as an array from pre-created collection.
On each call memory consumption grows by pretty huge value (~65kB) even though oci_free_statement()
is called.
The important conditions to reproduce:
1. Bind array contains references. Without those I get
639500
639520
2. PL/SQL script actually writes to one of bound variables. With the second (currently commented
out) version I get
639516
657136
Test script:
---------------
function query($data) {
global $conn;
$stid = oci_parse($conn, 'begin select :a + :b into :b from dual; end;');
//$stid = oci_parse($conn, 'declare j number; begin select :a + :b into j from dual;
end;');
oci_bind_by_name($stid, ':a', $data['a'], 100);
oci_bind_by_name($stid, ':b', $data['b'], 100);
oci_execute($stid);
oci_free_statement($stid);
}
$conn = oci_connect('user', 'pass', 'dbref');
if (!$conn) {
$e = oci_error();
die($e['message']);
}
$data = array();
for($i = 0; $i < 1000; $i++) {
$data[] = array(
"a" => 1,
"b" => 2
);
}
print memory_get_usage() . "\n";
for($i = 0; $i < 100; $i++) {
query(
array(
"a" => &$data[$i]["a"],
"b" => &$data[$i]["b"]
)
);
}
print memory_get_usage() . "\n";
oci_close($conn);
Expected result:
----------------
639500
7202720
Actual result:
--------------
639500
639520 or nor far from this
