Bug#916375: apache2: Segmentation fault when mod_perl.so is loaded

Thanks Niko,

it seems that you where right regarding libmariadbclient18 ...

downgrading libmariadbclient18 fixed the issue :-)

    dpkg -i libmariadbclient18_10.1.26-0+deb9u1_amd64.deb

	We are using unattended upgrades (security only), and we suspect that an automatic system update has installed a new Perl version that now causes these problems.
Have you ruled out the MariaDB update? That one seems the most
likely to have triggered this regression.


(Not sure how reliably you got the list of loaded shared libraries;
you seem to be running the prefork mpm so presumably only some of your
apache processes will have the libraries loaded by the actual Perl
