IBM IDS EXPRESS / 5724L2305 / C10 - IDS 12.10

The following query used to work in 11.50, 11.70 and in 
12.10.FC2, but fails in 12.10.FC3. 
 
SELECT A.tabid, (SELECT SUM(B.collength * A.rowsize) FROM 
syscolumns B WHERE B.tabid = A.tabid) 
FROM systables A 
WHERE A.tabid = 1; 
  294: The column (tabid) must be in the GROUP BY list. 
 
with the GROUP BY 
SELECT A.tabid, (SELECT SUM(B.collength * A.rowsize) FROM 
syscolumns B WHERE B.tabid = A.tabid) 
FROM systables A 
WHERE A.tabid = 1 GROUP BY 1;

If the order of the columns in the SUM() function is changed, 
the query completes correctly. 
SELECT A.tabid, (SELECT SUM(A.rowsize * B.collength) FROM 
syscolumns B WHERE B.tabid = A.tabid) 
FROM systables A 
WHERE A.tabid = 1;
