INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10

A simple query against TS using TODAY and adding or subtracting
creates an AF and errors:

Create dbaccessdemo7

 select * from ts_data_v where tstamp = (TODAY-1);

244: Could not do a physical-order read to fetch next row.
12803: Error in executing an access_method routine execution
sequence.

or just crashes engine.

Note that just using TODAY (no + or -) works fine. A literal
date cast to a DATE type also works. Also casting (TODAY-n) to a
datetime is also successful, e.g. the following works okay:

select * from ts_data_v where tstamp = (TODAY-1)::datetime year
to second;
