ID: 41899 Updated by: tony2001@php.net Reported By: geoffwa at cs dot rmit dot edu dot au -Status: Closed +Status: Assigned Bug Type: Streams related Operating System: Solaris 10 PHP Version: 5.2.3 -Assigned To: +Assigned To: tony2001 New Comment: I'm still able to reproduce it, though I'm not able to debug it since both GDB and GCC fail to compile on Solaris. I'm working on that atm..

Using an absolute path or a path with a non-'..' leading component opens said file just fine.
