Hi Stefan,
I've done as best as I can for this. Interestingly, when I started
again with an absolutely clean installation of apache2, with the only
changes from the default installation being:
* adding the CoreDumpDirectory directive to apache2.conf
* enabling the ruid2 module (but not the http2 module)
I still obtained the same failing behaviour (but not a crash)
This is the /var/log/apache2/error.log message:
[Wed Feb 08 21:15:03.829771 2017] [core:notice] [pid 6416:tid 140261767853248] AH00052: child pid 9982 exit signal Aborted (6)
Running gdb on process 6416 gave essentially nothing; see the attached
gdb2.out. (I pressed c after the page had failed to load, then did
ctrl-c to exit. Nothing displayed in the gdb trace.)
More interesting was the effect of attaching to the child process: see
the gdb.out attached.
I also did an strace on the child process; that is in strace.out.
What is very interesting is that I have had mod_ruid2 on another
machine (also running testing) and it hasn't had any problems.
It certainly looks as though the bug is in that module.
Best wishes,
Julian

# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.
# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
# /etc/apache2/
# |-- apache2.conf
# | `-- ports.conf
# |-- mods-enabled
# | |-- *.load
