Description:
------------
I'm trying to create a class that provides a layer between the programmer and the PDO native class.
When running the following code, Apache crashes. Only with the odbc PDO driver.

Thanks in advance.


Reproduce code:
---------------
class db
{
	protected $_Handle;
	function __construct($dsn)
	{
		$this->_Handle = new PDO($dsn);
	}
	public function DoSomething()
	{
		$a = $this->_Handle->prepare('SELECT * FROM valid_table');
		echo $undefined_variable; // or any other error
	}
}

function strange($errorNumber, $errorMessage)
{
	echo $errorMessage;
	exit; // if i take this out everything works as expected
}
set_error_handler('strange');

$a = new db('odbc:valid_connection_string');
$b = $a->DoSomething();

Expected result:
----------------
The $errorMessage reported by the error handler. And the script execution terminated.

Actual result:
--------------
Crash
