Or practically never. Almost every software has bugs. The amount of QA a piece of software needs to be bug free is astronomical. They made bug free auto pilot software for the Space Shuttle. For every hour of development, they spent three hours of QA. Imagine that. The full time QA staff was three times larger than the dev staff. Usually the ratio is the opposite of that: 1 QA per 3 devs.
