--------------------------------------
Summary: ARRAY<STRUCT<s: STRING> crashes in top-n
Key: IMPALA-12781
URL: https://issues.apache.org/jira/browse/IMPALA-12781
Project: IMPALA
Issue Type: Bug
Components: Backend
Reporter: Daniel Becker
Assignee: Daniel Becker
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:
{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 order by 1 limit 1{code}
The ASAN error message indicates a heap-use-after-free.
Note that this only happens if codegen is enabled.
