Description:
------------
PHP segfaults (with PDO_OCI) when PDOStatement throws an exception
while persistent connection is enabled. Running latest CVS version
(php5.2-200803010130) with the following config options ...
./configure --enable-debug --with-pdo-oci
Reproduce code:
---------------
<?php
try {
$dbh = new PDO('oci:dbname=//host:1521/ex', 'foo', 'bar',
array(PDO::ATTR_PERSISTENT => true));
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$stmt = $dbh->prepare('SELECT * FROM no_table');
$stmt->execute();
} catch (PDOException $e) {
print $e->getMessage();
}
$dbh = null;
?>
Expected result:
----------------
Print exception message:
SQLSTATE[HY000]: General error: 942 OCIStmtExecute: ORA-00942: table or
view does not exist
Actual result:
--------------
Segmentation fault
