--------------------------------------

             Summary: TMUDF returns wrong results with small numeric inputs
                 Key: TRAFODION-2615
                 URL: https://issues.apache.org/jira/browse/TRAFODION-2615
             Project: Apache Trafodion
          Issue Type: Bug
          Components: sql-cmp
    Affects Versions: 2.1-incubating
            Reporter: Hans Zeller
            Assignee: Hans Zeller
             Fix For: 2.2-incubating
         Attachments: EchoUdf.cpp

I got an incorrect result with this query:

{noformat}
>>select * from udf(echo(table(select * from (values (1), (22), (3), (4)) 
>>t(x))));

X     
------

     1
  -234
     3
   772

--- 4 row(s) selected.
>>
{noformat}

Note that -234 if FF16 (and 16 is hex for 22) and that 772 is 304, so it's a 
junk byte followed by the true values 22 and 4 that is returned.
