    Description

      In ASAN builds if we sort an array containing a struct of a string with limit, Impala crashes. This is how to reproduce it:

      In Hive:

      create table su (arr ARRAY<STRUCT<s: STRING>>) stored as parquet;
insert into su values (array(named_struct("s", "A")));

      In Impala:

      select 1, arr from su order by 1 limit 1

      The ASAN error message indicates a heap-use-after-free.

      Note that this only happens if codegen is enabled.
