  1) Some of the registers being used in 64 bit addressing mode
     for DB2 had not been initialized and had erroneous data in
     its high halves on entry from caller.
  
  2) Thread safe storage was not used when writing out a debug
     message causing S0C4 abend.
  
  3) Invalid address used to free 64 bit storage.
  

Problem conclusion

• 1) High halves of registers have been cleared
     to avoid S0C4 abend reported in DFS554A.
  
  2) Thread safe storage is used for DEBUG trace messages
     to avoid S0C4 abend in IEAVBWTO.
  
  3) Fixed SDC4 abend while freeing 64 bit storage.
