I have this problem too. Restarted my apache do the work, but this solution is temporary until that "mysterious" fatal error happen again.

The files in system should not be modified. My files were modified somehow and were throwing error. I resolved my problem as below.

Download fresh codeigniter and extract files
copy system files from fresh codeigniter into your project and overwrite the whole system folder.

This should fix your problem.
