Do both WordPress & your app need to be on the same subdomain? Why not put them on separate subdomains? Or have your app on the subdomain and WordPress as a subdirectory?
It mostly means that there is a php error. Try enabling debugging:

Note: By default, CodeIgniter displays all PHP errors. You might wish to change this behavior once your development is complete. You'll find the error_reporting() function located at the top of your main index.php file. Disabling error reporting will NOT prevent log files from being written if there are errors.
