Description:
------------
In the reproduce code we include a file "test.php" showing 'Hello World' six times:
 - Outside a destructor: "test.php"
 - Outside a destructor: "D:\server\www\test\test.php" (full path)
 - Outside a destructor: "./test.php"

These three cases work. We don't change include path and try them in a destructor:
 - Outside a destructor: "test.php" - works
 - Outside a destructor: "D:\server\www\test\test.php" (full path) - works
 - Outside a destructor: "./test.php" - No such file or directory, even if the file exists.

Outside a destructor, PHP parses correctly the include path, inside it seems to be broken, because a fatal error is generated. PHP manual doesn't explain why the last case doesn't work, I also can't find any reason. I hope you'll fix it quickly.

---Configuration---
Windows XP SP 2 (NTFS)
PHP 5.1.2
Apache 2.0.55
Ze1.compatibility = 0
Include path = .;C:\php5\pear (PHP 5 default)
Safe mode = off

Reproduce code:
---------------
test.php:
<?php
	echo 'Hello world!<br/>';
?>

problem.php:
<?php	
	require('test.php');
	require('D:\server\www\test\test.php');
	require('./test.php');

	class foo{
		function __destruct()
		{
			require('test.php');
			require('D:\server\www\test\test.php');
			require('./test.php');
		}
	}
	
	$foo = new foo;
?>

Expected result:
----------------
Hello world!
Hello world!
Hello world!
Hello world!
Hello world!
Hello world!

Actual result:
--------------
Hello world!
Hello world!
Hello world!
Hello world!
Hello world!
