Hello @petterreinholdtsen

The policy for the SQLCipher project is to minimize changes that diverge from upstream SQLite whenever possible. This allows us to minimize diffs against the base code and maintain a consistent process for applying core upstream fixes. Thus when issues are reported against SQLCipher that are actually rooted in the upstream SQLite project, i.e. the code originated in SQLite and affects both equally, we generally ask that they be reported to SQLite instead. This usually involves reproducing the issue with standard" SQLite (completely excluding SQLCipher), documenting the issue, and then submitting a summary and/or patch to the SQLite maintainers. If and when appropriate changes are applied to upstream SQLite, the SQLCipher project would then incorporate those fixes as part of our standard release workflow.

This pull request appears to fall into that category. The changes are not specific to SQLCipher or any of the project's extensions, so it would be better to address this with the SQLite project. While we really appreciate you taking the time to submit this pull request, we would not anticipate applying it against SQLCipher at this time. Please let me know if you have any questions.
