Wrong _realpath with 4 or more parent-directories

[SpazzMarticus]

Hi,

I got some wierd "Smarty: Unable to load template file" errors, and I followed them to the _realpath function in the Smarty class.

I tested the function by mocking getcwd to always return /0/1/2/3/4/5/6/7/8/9, set the DS constant to / and then tested _realpath with $realpath always being set to true.

Path: folder
Realpath: /0/1/2/3/4/5/6/7/8/9/folder

Path: ../folder
Realpath: /0/1/2/3/4/5/6/7/8/folder

Path: ../../folder
Realpath: /0/1/2/3/4/5/6/7/folder

Path: ../../../folder
Realpath: /0/1/2/3/4/5/6/folder

---

Wierd stuff occurs from here on:

Path: ../../../../folder
Realpath: /0/1/2/3/4/5/6/7/folder
Should be: /0/1/2/3/4/5/folder

Path: ../../../../../folder
Realpath: /0/1/2/3/4/5/6/folder
Should be: /0/1/2/3/4/folder

Path: ../../../../../../folder
Realpath: /0/1/2/3/4/5/folder
Should be: /0/1/2/3/folder

Path: ../../../../../../../folder
Realpath: /0/1/2/3/4/5/6/folder
Should be: /0/1/2/folder

Path: ../../../../../../../../folder
Realpath: /0/1/2/3/4/5/folder
Should be: /0/1/folder

Path: ../../../../../../../../../folder
Realpath: /0/1/2/3/4/5/6/folder
Should be: /0/folder

Can this be fixed, or is there any workaround?
