Bug #71560 [NEW]: segfault in zend_parse_parameters

From: sautier dot louis at gmail dot com Operating system: Linux (Archlinux) PHP version: 7.0.3 Package: FPM related Bug Type: Bug Bug description:segfault in zend_parse_parameters Description: ------------ Hi, I regularly run into crashes since I updated to PHP 7. My setup is quite standard: nginx + PHP-FPM for a Wordpress site. After running smoothly for a couple of days, the processes will start segfaulting. I'm running Archlinux's php-7.0.3-1 whose configuration can be seen at https://projects.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/php I have not yet been able to reliably reproduce the issue. All I know is that it happens after a few days and that a restart fixes it. Expected result: ---------------- Feb 09 13:30:46 kim kernel: php-fpm[16015]: segfault at 10 ip 0000000000691729 sp 00007fffccc439f0 error 4 in php-fpm[400000+89b000] Feb 09 13:30:46 kim nginx[566]: 2016/02/09 13:30:46 [error] 578#0: *145203 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: ******, server: website Feb 09 13:30:47 kim systemd-coredump[16036]: Process 16015 (php-fpm) of user 33 dumped core.
