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()
