Description:
------------
When an E_STRICT error is emitted from a class within a namespace and this is 
caught in a custom error handler, then require_once() fails.

To demonstrate this bug, I created a minimal test below. It consists of 3 files. 
Place them in a directory and execute test.php from the command line.

Test script:
---------------
************* file test.php ******************
<?php
error_reporting(E_ALL | E_STRICT);

// Custom error handler.
function handle_error($code, $message, $file, $line, $context) {
	$code = $code & error_reporting();
	if ($code == 0) { // skip @ suppressed errors.
		return;
	}
	$errors = array(
		E_ERROR				=> 'E_ERROR',
		E_WARNING			=> 'E_WARNING',
		E_PARSE				=> 'E_PARSE',
		E_NOTICE			=> 'E_NOTICE',
		E_CORE_ERROR		=> 'E_CORE_ERROR',
		E_CORE_WARNING		=> 'E_CORE_WARNING',
		E_COMPILE_ERROR		=> 'E_COMPILE_ERROR',
		E_COMPILE_WARNING	=> 'E_COMPILE_WARNING',
		E_USER_ERROR		=> 'E_USER_ERROR',
		E_USER_WARNING		=> 'E_USER_WARNING',
		E_USER_NOTICE		=> 'E_USER_NOTICE',
		E_STRICT			=> 'E_STRICT',
		E_DEPRECATED		=> 'E_DEPRECATED',
	);
	if (array_key_exists($code, $errors)) {
		$errname = $errors[$code];
	}
	else {
		$errname = $code;
	}
	$error = "Error handler caught $errname with message \"" . $message . '" at ' . $file . ' line ' . $line . ".\n";
	error_log($error);
	require_once('bla.php');
	bla($error);
	return;
}
set_error_handler('handle_error');

// This fails because bla.php can't be required in error handler:
require_once('Abstract.php');



*************** Abstract.php **************
<?php
namespace MyNamespace {
	abstract class AbstractFoo {
		abstract public static function foo(); // PHP 5.3 issues an E_STRICT here about abstract + static, even though it now supports static inheritance.
	}
}




*************** bla.php ******************
<?php
function bla() {
	print "You should see this.\n";
}

Expected result:
----------------
Error handler caught E_STRICT with message "Static function 
MyNamespace\AbstractFoo::foo() should not be abstract" at 
/home/cmanley/0/Abstract.php line 4.

You should see this.

Actual result:
--------------
Error handler caught E_STRICT with message "Static function 
MyNamespace\AbstractFoo::foo() should not be abstract" at 
/home/cmanley/0/Abstract.php line 4.

PHP Fatal error:  Call to undefined function bla() in /home/cmanley/0/Abstract.php
