The 404 problems (CI Reactor)

This is a valid point victorche that has nothing to do with SPL_Autoload.

The 404_override solution is a Routing solution. If when you call a URL it cannot find anything, it will route to the controller you specified. However once you call show_404() this will not try to route again as you are already in a controller.

This is not so much a bug, just an unexpected usage of the feature. To get this working would involve implementing a solution very similar to HMVC (not talking about Modular Extensions or any module functionality, just the ability to call another controller from a controller). This is a known topic, but for now I would just suggest you install HMVC and make a call to that controller, or redirect with a HTTP 1.1 Status 404 header set to let Google/Browser know the page was a 404.
