www/mod_php56: env WITH_DEBUG=3D1 make reinstall (prior to that, I had to "=
pkg delete" the
port www/mod_php56 first). When having mod_php56 rebuilt with DEBUG on as r=
ecommended and
performing command sequence to enter gdb, run -X, the Apache 2.4 now crashe=
s immediately
and not when the URL is called by the browser triggering the fault. This is=
 what I get
then:
