   @rdblue @RussellSpitzer, it was either the exception Russell mentioned or 
simply wrong results. I had two identical queries with and without 
vectorization and they were giving different results. Based on what I see, the 
underlying issue is the wrong logic for handling reused batches. When container 
reuse was enabled and we had multiple batches, the second batch would be 
corrupted. I'd appreciate extra attention to that part.
