Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same.
Thank you for your interest in PHP.

Description:
------------
When preparing a statement (see below) I get a whitescreen - the PHP
process seems to die without any error output, despite having
error_reporting = E_ALL and display_errors = On in my php.ini.
I'm using PDO Driver for MySQL, client library version 4.1.15
Reproduce code:
---------------
$pdo = new PDO([...]);
$statement = $pdo->prepare('SELECT r1.a AS a, r1.b AS b, 0 AS v1 FROM
`links` AS r1 WHERE r1.a = :a AND r1.b = :b LIMIT 0,1 UNION SELECT r1.a
AS a, r2.b AS b, r2.a AS v1 FROM `links` AS r1 JOIN `links` AS r2 ON
r1.b = r2.a WHERE r1.a = :a AND r2.b = :b AND r1.a != r2.a AND r2.b !=
r2.a LIMIT 0,1');
die('foo');
/* other queries with bound params work perfectly here= */
Expected result:
----------------
foo
Actual result:
--------------
Execution stops after calling PDO::prepare()
