= Description =

Table of contents mixed with pages that include /SubPage cause infinite recursion.

== Steps to reproduce ==
## Describe the steps needed to reproduce the bug. If we can't reproduce it, we  probably can't 
create this page:
{{{
[[TableOfContents]]

This page include its /SubPage:

[[Include(/SubPage)]]
}}}

Now click on the sub page link and create this page:
{{{
This page include its /SubPage:

[[Include(/SubPage)]]
}}}

And try to click "Show Parent"...

Try on this wiki: /SubPage
