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.
