INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10

You may observe wrong results when IFX_FOLDVIEW is active (set 
to 1 in the onconfig file). 
 
In the reported situation we have a CASE expression within the 
view that is being referenced in the SELECT statement. 
 
Depending on the query path chosen then an excess row was 
observed which does not match the filter. 
 
The SELECT statement is using ANSI JOIN and has predicate 
filters.

* PROBLEM DESCRIPTION:                                         * 
* A query may return incorrect results under the following     * 
* conditions:                                                  * 
*   - a view containing multiple tables, joined together with  * 
* ANSI INNER JOIN or Informix inner join                       * 
*   - a query with ANSI OUTER JOIN where the view is used as   * 
* dominant table, and one other table as subservient table     * 
*   - the view definition has an OR-clause predicate which     * 
* references more than 2 tables                                *
