Description:
------------
I found that
coll->append("string");
or
coll->assignElem(n,"string");
cause memory leak.

You need to free OCIAssignText()'ed strings with OCIStringResize() in oci8.c (PHP 4.4.6) and oci8_collection.c (PHP 5.2.1, PECL/oci8-1.2.3) because OCICollAppend() and OCICollAssignElem() perform deep-copy of element value.

Reproduce code:
---------------
$collStr = ocinewcollection( ... );
$collStr->append("string");              /* memory leak */
$collStr->assignElem(0,"string");        /* memory leak */

$collNum = ocinewcollection( ... );
$collNum->append(1234);                  /* no memory leak */
$collNum->assignElem(0, 5678);           /* no memory leak */

$collDate = ocinewcollection( ... );
$collDate->append("2007-01-01");         /* no memory leak */
$collDate->assignElem(0, "2007-02-02");  /* no memory leak */



Expected result:
----------------
no memory leak


Actual result:
--------------
memory leak

Are you using OCI8 from PECL?
If yes, which version?
