Description:
------------
The rename function says that renaming across partitions was fixed in 4.3.3, but it appears that it is broken in 4.3.8.

I have three partitions on my system:
/
/dev/shm
/tmp

I'm not sure if it matters, but the disk is mirrored with RAID level 1.

Trying to rename a directory that resides in "/tmp" to the "/" file system results in:

"Warning: rename(<from>, <to>): Is a directory in <script> on line XX."

and the <to> directory name is created as an empty file.

I moved the <from> directory to the "/" partition and then tried the rename again (using the same PHP code) and everything worked fine.

Please, provide a reproduce code so we can reproduce it ourselves.

# mkdir /tmp/test
# touch /tmp/test/foo.txt
# emacs test.php
<?
rename("/tmp/test", "/root/test");
?>

# /usr/local/php-4.3.8/bin/php test.php

Warning: rename(/tmp/test,/root/test): Is a directory in /root/test.php on line 2.

(A empty file "test" has now been created in /root directory)
# rm test
# mkdir /root/test
# touch /root/test/foo.txt
# emacs test.php
<?
rename("/root/test", "/root/test2");
?>
# /usr/local/php-4.3.8/bin/php test.php
( "/root/test" directory renamed to "/root/test2")

# emacs test.php
<?
rename("/tmp/test", "/tmp/test2");
?>
# /usr/local/php-4.3.8/bin/php test.php
("/tmp/test" directory renamed to "/tmp/test2")
