Debian version on our system is 9.6, and kernel version 4.14.86-0.
We don't see the crash with the following upstream fix for assertion failure:
commit 5b3cc0c86aeddd4615e7e28e79aa89e5b77a6507

journald: fix assertion failure on journal_file_link_data. (#5843)
When some error occurs during the initialization of JournalFile,
the JournalFile can be left without hash tables created. When later
trying to append an entry to that file, the assertion in
journal_file_link_data() fails, and journald crashes.
This patch fix this issue by checking *_hash_table_size in
journal_file_verify_header().

Changes:
systemd (232-25+deb9u10) stretch; urgency=medium
.
* journald: fix assertion failure on journal_file_link_data (Closes: #916880)
* tmpfiles: fix "e" to support shell style globs (Closes: #918400)
* mount-util: accept that name_to_handle_at() might fail with EPERM.
Container managers frequently block name_to_handle_at(), returning
EACCES or EPERM when this is issued. Accept that, and simply fall back
to fdinfo-based checks. (Closes: #917122)
* automount: ack automount requests even when already mounted.
Fixes a race condition in systemd which could result in automount requests
not being serviced and processes using them to hang, causing denial of
service. (CVE-2018-1049)
* core: when deserializing state always use read_line(…, LONG_LINE_MAX, …)
Fixes improper serialization on upgrade which can influence systemd
execution environment and lead to root privilege escalation.
(CVE-2018-15686, Closes: #912005)
