Another segfault on INSERT into source table for several MATERIALIZED VIEWs. #6245
Description
We are seeing segfaults on INSERT in ClickHouse installed on Ubuntu Xenial from stable deb packages from 19.11.2.7 onwards. From the backtraces I believe several are related, so am reporting these as a single issue. This was discovered while updating from 18.5.1 to 19.11.3.11. So far in our testing it appears 19.10.1.5 does not have the problem.
The segfaults are frequent, but cannot be reliably triggered by a particular insert. At this point we have not managed to isolate a simple method to reproduce, but hope the backtraces may give sufficient clues.
The inserts are to a simple table, but that table is in turn used as the source for a collection of MATERIALIZED VIEWs, using either SummingMergeTree or AggregatingMergeTree.
This may have the same underlying cause as #6244, but I'm not sure, so am filing as a separate issue.
