I have compiled php with --enable-debug and can extract everything you want from the core file, but I don't have a way to reproduce it. I am testing now 5.3 in production and this server is running with debug to catch problems. I have built php the following way: export CFLAGS="-O2 -msse -mmmx -msse2 -msse3 -mfpmath=sse" export CXXFLAGS="${CFLAGS}" ./buildconf ./configure --prefix=$PHPPREFIX \ --enable-fpm \ --with-libevent-dir=$LIBEVENTPREFIX \ --with-mysql \ --disable-ipv6 \ --disable-filter \ --disable-hash \ --disable-posix \ --disable-tokenizer \ --without-pear \ --without-sqlite \ --with-pdo-mysql \ --with-gd fpm ini: [global] pid = /usr/local/php-5.3-r299968/var/run/php-fpm.pid error_log = /usr/local/php-5.3-r299968/var/log/php-fpm.log log_level = notice emergency_restart_threshold = 10 emergency_restart_interval = 1m process_control_timeout = 5s daemonize = yes [www0] listen = xxx:9910 listen.backlog = -1 listen.allowed_clients = 127.0.0.1,xxx user = web group = web pm = dynamic pm.max_children = 50 pm.start_servers = 10 pm.min_spare_servers = 5 pm.max_spare_servers = 20 pm.max_requests = 500 pm.status_path = /status ping.path = /ping ping.response = pong request_terminate_timeout = 30s request_slowlog_timeout = 15s slowlog = /usr/local/php-5.3-r299968/var/log/php-fpm-0.log.slow rlimit_files = 20000 rlimit_core = 0 catch_workers_output = yes env[HOSTNAME] = $HOSTNAME env[PATH] = /usr/local/bin:/usr/bin:/bin env[TMP] = /tmp env[TMPDIR] = /tmp env[TEMP] = /tmp
