This seems to only affect sqlite versions older than 3.17 as, according to the sqlite developers and the reporter of the Ubuntu bug, the issue has been indirectly fixed in version 3.17.
For later versions the patch serves only to detect the issue earlier and to provide the user with a more useful error message.
