Description:
------------
Having a prepared statement with a given number of parameters (ie. ?,?) and binding two more parameters than required causes zend_mm_heap corruption where an error is expected.



Reproduce code:
---------------
// NOTE: I'm running PostgreSQL 8.2.3

$db = new e4_PDO($db_connect_string);

$item = array(112,113,114);

$sql = "SELECT * FROM item_table WHERE item_id IN (?)";
$stmt = $db->prepare($sql);

$stmt->bindValue(1,$item[0]);
$stmt->bindValue(2,$item[1]);
$stmt->bindValue(3,$item[2]);

$stmt->execute();



Expected result:
----------------
something like:
ERROR:  bind message supplies 3 parameters, but prepared statement "pdo_pgsql_stmt_XXXXXXXX" requires 1

Actual result:
--------------
zend_mm_heap corrupted

I compiled and installed the latest CVS snapshot but the problem still persists. The Same code returns the same error.

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.
