| | | | | | | | | | | | | | | | counter at offset 24 matches the version number counter at offset 92. This prevents corruption in the case of two applications writing to the database where one is an older version of SQLite and the other is a newer version.

* Store the MemPage structure in memory following, instead of preceding, the ↵dan2010-06-10
