> --------------------------------------------
>
> Key: IMPALA-10703
> URL: https://issues.apache.org/jira/browse/IMPALA-10703
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 3.4.0
> Reporter: Gabor Kaszab
> Assignee: Amogh Margoor
> Priority: Major
> Labels: complextype, orc
>
> Repro steps:
> - Issue only happens in debug build as apparently there is a DCHECK failing.
> - You have to launch Impala with --log_level=3 option to increase the log level.
> - Then running this query crashes Impala:
> {code:java}
> select inner_arr.ITEM.e from functional_orc_def.complextypestbl tbl, functional_orc_def.complextypestbl.nested_struct.c.d.ITEM inner_arr;
> {code}
>
> Backtrace (relevant part):
> {code:java}
