Hi, I have a compatibility problem with my vfs implementation of memory databases. I once implemented it successfully probably with a version 3.6.something. Today I tried to create a new database using the same code with the latest (3.11.1) version (the procedure is when no prior db data exists, i.e. absolutely new file is being worked with) and it failed on a first write-related query, something like "create table if not exists" . After that I decided to try different binary versions of sqlite and narrowed it down to the difference between 3.8.2 and 3.8.3. So, with 3.8.2 everything is ok, the db created has correct structure (checked on the memory block saved as file) and no error produced during the creation. With 3.8.3 the first attempt to perform the same query on a new file produces "Sql logic error or missing database".
As I see from the version history page that no specific vfs-related changes for 3.8.3 were reported, only a major change that can affect structure and vfs is initial common table expressions implementation. What are the changes that might trigger the change? Thanks, Max
