  Code analysis has found that there are some cases where a zero
  pointer could be used to reference storage.  However, no
  problems have been reported resulting from it but this could
  cause an abend or other unpredictable results.
  

Problem conclusion

Temporary fix

Comments

• DB2 code has been modified to check pointer before using it to
  reference storage. This will help prevent unexpected abends or
  possibly unpredictable results.
