Without this fix, if an index scan is run on the table - within the view on the right-hand side of the LEFT JOIN, stale result - registers might be accessed yielding incorrect results, and/or an - OP_IfNullRow opcode might be invoked on the un-opened table, resulting in a - NULL-pointer dereference.
