      Description

      We are testing how impala functions using our old code paths now that we have added memory spilling.

      I started Impala with ../bin/start-impala-cluster.py -impalad_args="-enable_partitioned_aggregation=false --enable_partitioned_hash_join=false"
      and I am able to reproduce the bug by running
      py.test query_test/test_chars.py -k TestStringQueries -x --exploration_strategy=core --workload_exploration_strategy=functional-query:core

      When I looked at the core I traced the issue back to a failed dcheck in be/src/codegen/codegen-anyval.cc on line 540
      char is an unsupported type here
