On WMF wikis (like mediawiki.org), the {{#language:}} parser function provided by Extension:CLDR [1] throws on MediaWiki wikis a Fatal exception of type MWException when for the second parameter you put some special characters.

Those are what I've tested so far and produce the exception:

 < > ' " : [ ] ( ) / &

Example input that produces the error:

{{#language:es|<}}

Works just doing a preview.

I've installed CLDR extension on current master, and it doesn't throw that error for me. I've tried without caching, with memcache and with database cache, but I was unable to reproduce the problem, hence filing under Wikimedia product instead of Extensions/CLDR
