--- Comment #2 from O. Hartmann <ohartmann@walstatt.org> ---
I followed an advice checking the debugging output on apache24 when it cras=
hes.
I can provide the following (minimalistic) information:

[ from starting recent www/apache24 with gdb ]

lang/php56 is compiled with option ZTS enabled.

www/mod_php56 has the following options set:

=3D=3D=3D> The following configuration options are available for mod_php56-=
5.6.33:
     AP2FILTER=3Doff: Use Apache 2.x filter interface (experimental)
     PHPDBG=3Doff
     DEBUG=3Doff: Enable debug
     DTRACE=3Doff: Enable DTrace support
     IPV6=3Don: IPv6 protocol support
     MAILHEAD=3Doff: Enable mail header patch
     LINKTHR=3Don: Link thread lib (for threaded extensions)
     ZTS=3Don: Force Zend Thread Safety (ZTS) build
=3D=3D=3D> Use 'make config' to modify these settings

Option ZTS is strongly recommende, even required, when having a threaded Ap=
ache
server.
