David Wayne Birdsall commented on TRAFODION-2131:
-------------------------------------------------
The problem was first noticed on a test table involving an INTERVAL YEAR(1) TO
MONTH column. When UPDATE STATISTICS was done on such a table (and there was
data in it), we would get a core like the following:

Later, it was noticed that similar cores occur on TINYINT columns as well.
