New Comment:

Description:
------------
A segmentation fault results when the pdo_oci driver receives an error
message from the oracle server.
Reproduce code:

<?php
try {
$pdo = new PDO("oci:dbname=instance", "bad_user", "bad_pass",
array(PDO::ATTR_PERSISTENT => true));
} catch (Exception $e) {
echo "Caught exception: ", $e->getMessage(), "\n";
}
Expected result:
----------------
Caught exception: SQLSTATE[42S02]: pdo_oci_handle_factory: ORA-12154:
TNS:could not resolve the connect identifier specified
(/opt/php/src/ext/pdo_oci/oci_driver.c:462)
