[-- Attachment #1 --] Hi, I confirm that it happens on my setup as well. Have you tried to build official PHP-8.1.6 instead using the one from ports? It seems it works. I tried with freebsd:~/php-src # git status HEAD detached at origin/PHP-8.1.6 nothing to commit, working tree clean freebsd:~/php-src # freebsd:~/php-src # ./buildconf freebsd:~/php-src # ./configure --without-iconv --enable-shared --with-apxs2 freebsd:~/php-src # make -j4 freebsd:~/php-src # make install Regards, Wojtek >>>>> Running 13.1-RELEASE with everything installed from packages and aslr enabled, apache24 will core dump on a graceful restart after installing php81-extensions. Start with apache24, php81 and mod_php81 installed /usr/local/etc/rc.d/apache24 start apache is running /usr/local/etc/rc.d/apache24 graceful apache is still running Then install php81-extensions: /usr/local/etc/rc.d/apache24 stop pkg install php81-extensions /usr/local/etc/rc.d/apache24 start apache is running /usr/local/etc/rc.d/apache24 graceful kernel: pid 2122 (httpd), jid 0, uid 0: exited on signal 11 (core dumped) This is with using all the default conf files. If I disable aslr it works fine. I'm enabling aslr by adding these lines to /etc/sysctl.conf and rebooting. kern.elf32.aslr.enable=1 kern.elf32.aslr.pie_enable=1 kern.elf32.aslr.honor_sbrk=0 kern.elf64.aslr.enable=1 kern.elf64.aslr.pie_enable=1 kern.elf64.aslr.honor_sbrk=0 This is the first time I've tried enabling aslr so maybe I'm doing something wrong.
