#45835 [NEW]: include_once ans symlinks

From:             hannes dot magnusson at gmail dot com
Operating system: Ubuntu 8.04.1
PHP version:      5.3CVS-2008-08-16 (snap)
PHP Bug Type:     CGI related
Bug description:  include_once ans symlinks

Description:
------------
Looks like the new realpath() implementation is having issues with
symlinks..

include_once with symlinks in the path, under lighttpd, is failing.
Can't seem to reproduce this under cli.

/www/bjori.php.is is a symlink to /www/local.php.net
/www/local.php.net is then a symlink to /home/bjori/php/web

Using the realpath of the file, or relative path, works fine.

Reproduce code:
---------------
bjori@lindsay:~/php/5.3$ cat config.nice
#! /bin/sh
#
# Created by configure

'./configure' \
'--prefix=/home/bjori/.apps' \
'--enable-debug' \
'--with-zend-vm=GOTO' \
'--disable-all' \
'--without-pear' \

bjori@lindsay:~/php/web$ cat test.php 
<?php
var_dump(file_exists("/www/bjori.php.is/test/inc.php"));
include  "/www/bjori.php.is/test/inc.php";

bjori@lindsay:~/php/web$ cat test/inc.php 
hello world


Actual result:
--------------
bool(true)
Warning: include(/www/bjori.php.is/test/inc.php) [function.include]:
failed to open stream: No such file or directory in
/home/bjori/php/web/test.php on line 3


Sometimes: 
bool(true)
Warning: include(/www/bjori.php.is/test/inc.php) [function.include]:
failed to open stream: Success in /home/bjori/php/web/test.php on line 3

And even the occasional:
Fatal error: Unknown: Failed opening required '' (include_path='.:') in
Unknown on line 0
