> The problem seems to be that we call
> {{output_partition_->aggregated_row_stream->Close()}} in
> be/src/exec/grouping-aggregator.cc:284 when hitting the limit, and then later
> the tuple creation in {{CleanupHashTbl()}} in
> be/src/exec/grouping-aggregator.cc:341 reads from poisoned memory.
> A similar query does not show the crash:
> {code:sql}
> select count(*) from functional_parquet.alltypes a group by a.string_col
> limit 2;
> {code}
> [~tarmstrong] - Do you have an idea why the query on a much smaller dataset
> wouldn't crash?
