I've been patching a configuration user interface web application that uses the same codebase for a bunch of different product categories. Some 40 files totaling 15000 lines of HTML/js combining filepp preprocessing (a C-like build time pre-processor) and SSI (server-side includes and conditional rendering with directives snuck into HTML comments) split over several repositories that are all tightly interdependent. Adding to that, obviously no one wants to claim ownership over this codebase and changes are frequently made by people that understandably don't know exactly what they're doing and reviewed by other people shooting from their hips. Any change to it has to be considered for every product that uses it, which I've never seen a full list of. Not too many LOC but the badness/LOC ratio is terribly high.
