Comment(by amattie):

 I don't have anything public to test this against. It's a server-level
 setting in IIS 7, so when I turn it on on our public-facing production
 servers, it'll break for all the applications for the users who are
 already hitting our servers with that class. Again, deflate is off by
 default on IIS w/o much of a reason to enable it unless then know about
 PHP < 6 not supporting gzip decoding, so I think that's why no one else
 has noticed it until now.

 Adding the following to the top of the compatible_gzinflate fixes the
 issue for my specific circumstances:

 {{{
 if ( false !== ($data = gzinflate($gzData)))
         return $data;
 }}}

 The fix remains untested for other server configurations.
