Queries to reproduce the crash using the testdata:
{code:sql}
create table bigstrs stored as parquet as
  select *, repeat(uuid(), cast(random() * 100000 as int)) as bigstr
  from functional.alltypes;

set MAX_ROW_SIZE=3.5MB;
set MEM_LIMIT=4GB;
create table my_str_group stored as parquet as
  select group_concat(string_col) as ss, bigstr
  from bigstrs group by bigstr;
{code}
