Simpler test case: http://meta.wikipedia.org/wiki/Sandbox

This is caused by the use of preg_replace() in the handling of pre,
nowiki, and math tags in addWikiText() (OutputPage.php). I added a hack to
escape $ characters a while ago, but apparently there's more. preg_quote()
would, you would think, handle this, but it seems to put in too much, and
you get slashes on your linebreaks.

Ugh.
