Description:
------------
pdo_oci crash when trying to connect to db with bad instance name/or user name/ or password, or db is down.



Reproduce code:
---------------
make $db to point to not existing db instance/to db which is down

include("config.inc");
    try{
      $this->conn = new PDO($db, $db_username,$db_password, 
			    array(PDO::ATTR_PERSISTENT => true));
    }catch (PDOException $e)
    {
    	include("config.inc");
		$logger =  &Log::singleton('file', $file, 'DBManager.php', $conf, $logLevel);
		$logger->log("Failed connecting to DB: ".$e->getMessage(), PEAR_LOG_ERR);
	//	$logger->log("DB error. Continuing without DB.", PEAR_LOG_INFO);
    }

Expected result:
----------------
It's expected that "catch" statement will catch the exception

Actual result:
--------------
script crashes with message in apache log:

*** glibc detected *** free(): invalid pointer: 0xb71e6ec4 ***
[Mon Jul 23 09:08:17 2007] [notice] child pid 7065 exit signal Aborted (6)

I'm unable to reproduce this issue with PHP 5.3.0-dev using the following script:

<?php
try {
    $db = new PDO("oci:dbname=nosuchthingsasthis", "test", "foo", array(PDO::ATTR_PERSISTENT => true));
} catch (PDOException $e) {
    print $e->getMessage();
}
?>

I get no crash but the expected error message "SQLSTATE[42S02]: pdo_oci_handle_factory: ORA-12154: TNS:could not resolve the connect identifier specified".

Can you please try again with a 5.3.0 snapshot from http://snaps.php.net/? Thanks!
