# The schema is malformed in that it has a subquery on a generated
# column expression. This will be loaded if writable_schema=ON. SQLite
# must not use such an expression during code generation as the code generator
# will add bits of content to the expression tree that might be allocated
# from lookaside. But the schema is not tied to a particular database
# connection, so the use of lookaside memory is prohibited. The fix
# is to change the generated column expression to NULL before adding it
# to the schema.
