Hi Moritz,
Even after a full restart (systemctl restart apache2), it still causes a
segfault on every "apache2ctl graceful".
vagrant up (debian/bullseye64)
sudo -i
apt update
apt install apache2; apt install libapache2-mod-auth-openidc
systemctl restart apache2
apache2ctl graceful
/var/log/apache2/error says:
[Wed Feb 23 09:54:04.187005 2022] [core:notice] [pid 2554:tid
140034803486016] AH00052: child pid 2678 exit signal Segmentation fault (11)
following every "apache2ctl graceful".
regards
Hamish

Dear Hamish,
sorry, I didn't think all the way through what you were writing.
Actually, enabling (and probably disabling) modules in Apache2 always
requires a restart of the main daemon process - so performing a
graceful restart/reload is simply not supported here (you are
experiencing the actual reason for that).
That's also why I wasn't able to reproduce in the first place -
because I restarted Apache after installing the Module out of muscle
memory. ;-)
Hope that helps,
Moritz

I'm seeing this in bullseye with a brand new apache install. Every
graceful restart (apache2ctl graceful) causes a segfault.
I don't have PHP or any other non-fault modules installed.
To reproduce: Set up fresh VM; apt install apache2; apt install
libapache2-mod-auth-openidc; apache2ctl graceful

This did not occur in buster.
