Well...yes ;). Look at the tarball first, it's harmless.

I could not find another way to reproduce it (yet) but in /; the tarball
seems to be the easiest way to make someone else reproduce it.
Thx,
Stephan

1) Create a symlink in / to /
root@thekid:/ > ln -s / phptest
root@thekid:/ > ls -al /phptest
lrwxr-xr-x 1 root wheel 1 May 21 10:40 /phptest -> /
2) Verify
root@thekid:/ > echo "OK" > /phpfile
root@thekid:/ > php -r 'include("/phptest/phpfile");'
Expected result: "OK"
3) Clean up
root@thekid:/ > rm /phptest /phpfile
You need to be root because you're working in /, that's it:)

Description:

Tarball: http://stephan-suerken.de/tmp/php53include.tar.gz
Hi,
with a certain directory setup (symlink pointing to /, see file tree in
php53include.tar.gz) plus script call syntax (see scripts "ok" and
"fail" scripts in tarball), including a file meekly fails.
I have not completely debugged it, but afaics "php_resolve_path" fails
were it should not; I suspect some of the "canonize path" functions
wrongly give an error here.
Thanks,
Stephan
Test script:
---------------
Steps to reproduce:
1. Download: http://stephan-suerken.de/tmp/php53include.tar.gz
[as root]
2. cd /
3. tar xfz php53include.tar.gz
4. /phptest/fail
Expected result:
----------------
# manwe(CHROOT:sid-ui): /phptest
# root? ./ok
/phpinclude/inc123.php: OK, INCLUDED
Actual result:
--------------
# manwe(CHROOT:sid-ui): /phptest
# root? ./fail
PHP Warning: require(/phplink/phpinclude/inc123.php): failed to open
stream: No such file or directory in /phptest/test.php on line 2
PHP Fatal error: require(): Failed opening required
'/phplink/phpinclude/inc123.php'
(include_path='.:/usr/share/php:/usr/share/pear') in /phptest/test.php
on line 2
