  1. When aceesing KSDS dataset with LSR+DFR options,
  some buffers might be lost because of the error in IKQBFB.
  2. Memory leak in the IJBVSM subpool on CA split
  when >16 LSR strings active.
  

Problem conclusion

• 1. Problem cause discovered in IKQBFB code.
  Wrong BCB field was checked for comparison.
  2. Memory leak was caused by IKQCAD code.
  Invalid Freevis length parameter was specified.
