Bug description: Memory leak when fetching timestamp column from Oracle
database
Description:
------------
PHP (debug build) detects memory leaks on this environment.
- Linux Cent OS 5.3 (64bit)
- unixODBC-2.2.15pre
- Oracle instantclient 11.1
This occurs only when fetching Oracle "TIMESTANP" column on Linux.
Reproduce code:
---------------
<?php
$dsn = "VALID_DATA_SOURCE_NAME";
$user = "VALID_USER_NAME";
$pass = "VALID_PASSWORD";
$conn = odbc_connect($dsn, $user, $pass);
// sample table has this schema and has more than one row(s).
// CREATE TABLE TEST (COLUMN1 TIMESTAMP)
$ret = odbc_exec($conn, "SELECT COLUMN1 FROM TEST");
// Here detects leaking memory!! And, data seems normal state.
$data = odbc_result($ret, 1);
var_dump($data);
odbc_close($conn);
Actual result:
--------------
string(26) "2009-11-13 00:00:00.000000"
