DB2 FOR LUW / DB2FORLUW / A50 - DB2

The DB2 instance may crash when attempting to create a stored 
procedure that contains a CALL statement that includes an 
aggregate function as an argument.  This could happen if the 
aggregate function was meant to be defined as a variable but was 
not properly declared. 
 
For example, the following CREATE PROCEDURE statement could 
cause this failure: 
 
CREATE PROCEDURE P2() 
  BEGIN 
     CALL P1(COUNT); 
  END 
 
A trap file will be produced containing a stack trace that looks 
like this:

With this APAR, DB2 will instead return a proper error message 
on the CREATE PROCEDURE statement. 
 
For example, it will now return: 
 
SQL0120N  Invalid use of an aggregate function or OLAP function. 
SQLSTATE=42903
