.... that's very different from what's stated in the article, and is actually what I'd expect to be the real problem. Dwelling on versions seems to be beside the point.
Sorry if the article is unclear. My intent was to clearly communicate that the problem can happen with any two instances, not necessarily of different versions. Like the nutshell summary at the top says.
But I also think that talking about different versions of SQLite is relevant, since dealing with those issues is one of the things that can lead an app developer toward the problem.
