Disable the result-set alias cache when on conditional code branches. Ticket #3461. The column cache and result set alias cache mechanisms are prone to this kind of error and need to be refactored. This check-in should be considered a temporary fix in advance of a more general redesign of the whole mechanism. (CVS 5841) check-in: 1fa3bbd8 user: drh tags: trunk
