Description Beau 2012-04-22 11:01:04 UTC 
1. Create an index page named Index:1 with a link to Page:1.png.
2. Create a page Page:1.png with the following content:
<pages index="1" from="1.png" to="1.png" />

3. Create a page in the main namespace with the following content:
<pages index="1" from="1.png" to="1.png" />

You will get: Fatal error: Maximum function nesting level of '100' reached,
aborting! This should be handled more gracefully.
Comment 1 Beau 2012-04-22 11:06:08 UTC 
I have submitted a change https://gerrit.wikimedia.org/r/#q,Ic4e878dec84a4cde8ebb455dee5370b1deaaa4f1,n,z for review. This change disables nested <pages> transclusion completely.
Comment 2 Beau 2012-04-24 14:43:16 UTC 
Similar case to bug 36157. It turns out MediaWiki can handle this situation (I had enabled unconfigured xdebug extension), however the result is quite ugly: https://test2.wikipedia.org/wiki/Beau%27s_playground so I recommend the fix to be merged.
