This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
To report this bug, see http://kb.askmonty.org/en/reporting-bugs
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Server version: 10.1.8-MariaDB-log
key_buffer_size=16777216
read_buffer_size=4194304
max_used_connections=1
max_threads=130
thread_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 817738 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

I've added the full log.
It shows 10.0.21 shutdown then all of the 10.1.8 stuff before I kill 10.1.8

Thanks for the info, can you provide the db for investigation ?
You can upload compressed and tar'ed db to ftp://ftp.askmonty.org/ there is private directory.

Ok, just a mysqldump --all-databases ... or a tar/gzip of the data folders?
Just tar/gzip all of the data folders, mysqldump could remove the problem.

The direct parent is 0eb84da14712a9ca820533dbc1d911b3aead1658, it starts all right.
Good news ... it looks like you can reproduce the issue.
I'll stay on 10.0.x for now as it's a production system and I don't have much time window to try again.
I can probably try again next week, but methinks I need to wait for 10.1.9
Thanks Elena, confirmed your observation. Now I need to figure out what is wrong with that change. Actual change is very small but it seems to have some hidden effect on purge.

commit 25f8738112b05f33cfa45eabfebf6edfc80e6d8a

MDEV-9040: 10.1.8 fails after upgrade from 10.0.21
Analysis: Lengths which are not UNIV_SQL_NULL, but bigger than the following
number indicate that a field contains a reference to an externally
stored part of the field in the tablespace. The length field then
contains the sum of the following flag and the locally stored len.
This was incorrectly set to
define UNIV_EXTERN_STORAGE_FIELD (UNIV_SQL_NULL - UNIV_PAGE_SIZE_MAX)
When it should be
define UNIV_EXTERN_STORAGE_FIELD (UNIV_SQL_NULL - UNIV_PAGE_SIZE_DEF)
Additionally, we need to disable support for > 16K page size for
row compressed tables because a compressed page directory entry
reserves 14 bits for the start offset and 2 bits for flags.
This limits the uncompressed page size to 16k. To support
larger pages page directory entry needs to be larger.
