8966520801 Added "assert_cast" function as a replacement for static_cast for columns 2019-08-21 05:28:04 +03:00

9df09f3506 Do not access shared arenas in aggregate function columns. 
These arenas may be updated concurrently, so it is unsafe to
access them, as illustrated by issue #4402. Store them separately
and use a different arena for the updates. Change some callers
to accomodate for this.
