Description:
------------
I'm trying to connect to my Oracle 10g DB, running on the same machine and mistyped dbname ("oci:dbname=orama" instead of "oci:dbname=oramax").
After execution i've got Segmentation fault. After doing some little research, i've found that segfault appears only if PDO_ATTR_PERSISTENT is set to true.

GDB output was:

Reproduce code:
---------------
<?php
$m_DSN = "oci:dbname=orama";
$m_user = "scott";
$m_password = "tiger";
try {
  $m_dbh = new PDO($m_DSN, $m_user, $m_password,
    array(PDO_ATTR_PERSISTENT => true));
  echo "Success!\n";
} catch (PDOException $e) {
  echo $e->getMessage();
  die("\nFailure :(\n");
}
?>

Expected result:
----------------
