> In ASAN builds if we UNION ALL an array containing a struct of a string with itself Impala crashes. This is how to reproduce it:
> In Hive:
>  
> {code:java}
> create table su (arr ARRAY<STRUCT<s: STRING>>) stored as parquet;
> insert into su values (array(named_struct("s", "A")));
> {code}
> In Impala:
> {code:java}
> select 1, arr from su
>   union all select 2, arr from su;{code}
> The ASAN error message indicates a heap-use-after-free.
