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

2018-12-18 Thread Hans-Georg Thien

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
application.)

Bug#916375: question about your solution

2018-12-14 Thread Hans-Georg Thien

Hi,

we have already tried that too. But (to my surprise) no change regarding 
the SEGV problem.

Hi,

If you suspect perl 'security update, you might want to try reverting 
to the previous version:


apt-get install libperl5.24=5.24.1-3+deb9u4

Br,

Cyrille
