Yes, see the line above, there's SIGSEGV in PID 1.
(Given the other SIGSEGVs, it looks like a common cause across different
processes, e.g. screwed libc update or similar.)

Also, based on the same line, you may be able to extract the coredump
from /var/lib/systemd/coredump (depends on coredump.conf:Storage=) and
figure out more.
