--- Comment #5 from Martin Tessun ---
So after some issue (systemd-coredump wasn't installed), I have a coredump now
- generated by simply doing systemctl reload apache2.
Some info:
$ sudo coredumpctl info --no-pager
PID: 2508 (httpd-prefork)
UID: 0 (root)
GID: 0 (root)
Signal: 11 (SEGV)

Message: Process 2508 (httpd-prefork) of user 0 dumped core.

So this looks like mod_php7 is causing the crash during reload in the
module_shutdown code.
If the complete core is needed or specific information besides the backtrace is
needed, let me know.
