mysqldump: Got error: 2013: "Lost connection to MySQL server during query" when using LOCK TABLES

2019-02-22 10:14:02 0x7f104844c700  InnoDB: Assertion failure in file /build/mariadb-10.3-L3F6cy/mariadb-10.3-10.3.12/storage/innobase/btr/btr0pcur.cc line 459

InnoDB: Failing assertion: page_is_comp(next_page) == page_is_comp(page)

InnoDB: We intentionally generate a memory trap.

InnoDB: Submit a detailed bug report to https://jira.mariadb.org/

InnoDB: If you get repeated assertion failures or crashes, even

InnoDB: immediately after the mysqld startup, there may be

InnoDB: corruption in the InnoDB tablespace. Please refer to

InnoDB: https://mariadb.com/kb/en/library/innodb-recovery-modes/

InnoDB: about forcing recovery.

190222 10:14:02 [ERROR] mysqld got signal 6 ;

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 https://mariadb.com/kb/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: 10.3.12-MariaDB-2

key_buffer_size=16777216

read_buffer_size=131072

max_used_connections=1

max_threads=153

thread_count=7

It is possible that mysqld could use up to 

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 352701 K  bytes of memory

Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x55aa81d57cb8

Attempting backtrace. You can use the following information to find out

where mysqld died. If you see no messages after this, something went

terribly wrong...
