INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10

Running a query selecting the rowid in the selection list and 
executing the query by a multi-index scan; 
for example in a query like this: 
 
   select 
        pb_in.rowid from  g_country pr_orig_country , pb_in 
where 
    pb_in.store_date between '01/01/2014' and '09/10/2014' and 
    pr_orig_country.iso_a2='VA' and pb_in.dept_code = '99' and 
pb_in.pb_num 
    >= 0 and pb_in.product_origin = pr_orig_country.id 
 
  1) informix.pr_orig_country: INDEX PATH 
 
    (1) Index Name: informix.country_uidx01 
        Index Keys: iso_a2 valid_till   (Serial, fragments: ALL) 
        Lower Index Filter: informix.pr_orig_country.iso_a2 = 
'720' 
 
  2) informix.pb_in: MULTI INDEX PATH (SKIP SCAN) 
 
may case a memory block header corruption for instance in this
