Hi,
I've just tested with php 5.3.10, the bug is still here.
Do you still need me to test with version 5.3.9 ?
Here is the proof:
root@djavanubu:/root#
root@djavanubu:/root# cat b.php
#!/usr/local/bin/php
root@djavanubu:/root#
root@djavanubu:/root# /usr/local/bin/php -v

Please confirm so I can look into it
Thanks

unlink() function truncates the file path name argument in some cases.
This bug appears also with the rename() function in the same cases.
The given source code use link() to duplicate a file, then unlink() to remove
the
source file. link() function works and unlink() bugs.
Test script:
---
#!/usr/local/bin/php
Expected result:
unlink() should remove the "/mnt/M://BRASIL/Carlinhos Brown/Alfagamabetizado -
Angel's Robot List.mp3" file
Actual result:
--
root@djavanubu:/# ./b.php
Warning: unlink(BRASIL/Carlinhos Brown/Alfagamabetizado - Angel's Robot
