Informix - Problem description

Problem IT30687 Status: Closed

ASSERT FAILURE / -874 : GENERAL EXCEPTION ERROR HAS OCCURRED IN THE
OPTIMIZER WHEN EXISTS CLAUSE USED WITH TIMESERIES VTI TABLE

product:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problem description:
The following query produces an Assertion Failure and is
returning error -874 (General exception error has occurred in
the optimizer):

SELECT 1 AS TIME_COMPONENT  FROM    VT_VEE_RDNG_INTVL I

  WHERE CORP_CD_ESI_ID =     '' AND
                RDNG_TYPE = '' AND
                ENRGY_DIR = '' AND
                RDNG_DTMGMT > '2014-01-01 05:15:00'     AND
               RDNG_DTMGMT BETWEEN '2019-05-15 05:15:00' AND
'2019-08-15 05:00:00' AND
               RDNG_FLG =  AND
    EXISTS (   SELECT 1  FROM     VALID_TENANT_DATA_WORK
                WHERE BATCH_ID =  AND
                    PREM_H =  AND
                    CA_OPEN_D  I.RDNG_DTMGMT);

Same query without the EXISTS clause runs OK.

The stack looks like:
