Rare has a history of video games that work in testing and have bugs buried in them for years until some novel architecture surfaces them. Not to imply other companies don't; just that Rare is an easy-to-reference name on the topic.

Donkey Kong 64 has a memory leak that will kill the game after a (for that era) unlikely amount of contiguous time playing it (8-9 hours, if I understand correctly). That was not caught in development but is a trivial amount of time to rack up if someone is playing the game and saving progress via emulator save-state instead of the in-game save feature.

(Note: there is some ambiguous history here. Some sources claim the game shipping with the Memory Pak was a last-ditch effort to hide the bug by pushing the crash window out to 13-20 hours instead of 8-9. I think recent research on the issue suggests that was coincidence and the game didn't ship with either Rare or Nintendo being aware of the bug).
