Bug #71192 [Opn]: Segfault on Shutdown

Edit report at https://bugs.php.net/bug.php?id=71192&edit=1 ID: 71192 Updated by: laruence@php.net Reported by: michael at currinda dot com Summary: Segfault on Shutdown Status: Open Type: Bug Package: Reproducible crash Operating System: Ubuntu Precise PHP Version: 7.0.1 Block user comment: N Private report: N New Comment: try with: USE_ZEND_ALLOC=0 ZEND_DONT_UNLOAD_MODULES=1 valgrind php7 yourscript.php it will shows where the problem came from, and I guess it probably relates to YAML. Previous Comments: ------------------------------------------------------------------------ [2015-12-22 07:48:50] michael at currinda dot com Unfortunately I wouldn't be able to test it without YAML, this is on a live server. There doesn't seem to be a huge amount of rhyme or reason to the actual scripts that are crashing it. I've had a case where the same script, with slightly different database inputs ie. a different record is crashing it. I've also downloaded the database to my local machine, run the script on local (mac running same version, though not compiled) and it hasn't crashed. ------------------------------------------------------------------------ [2015-12-22 05:44:23] seander@php.net Hi michael! Do you get this segfault as well with YAML not installed? What version of YAML do you have installed. Is there a specific script that is causing this, if so are you able to post it? thanks ------------------------------------------------------------------------ [2015-12-22 04:58:00] michael at currinda dot com Description: ------------ Segfault on shutdown, not sure what script is causing this but getting reports of unclean exits from browsers. Compiled with: './configure' \ '--prefix=/usr/local' \ '--with-libdir=/lib/x86_64-linux-gnu' \ '--with-mysqli' \ '--enable-fpm' \ '--with-readline' \ '--with-pdo_mysql' \ '--with-curl' \ '--enable-pcntl' \ '--enable-mbstring' \ '--enable-debug' \ '--with-zlib' \ '--with-pdo' \ '--enable-so' \ '--with-mcrypt' \ '--with-gd' \ '--enable-gd-native-ttf' \ '--with-openssl' \ '--with-png-dir=/usr' \ '--with-jpeg-dir=/usr' \ '--with-freetype-dir=usr' \ '--with-ttf' \ '--with-exif' \ '--enable-bcmath' \ also has PECL YAML extension installed.
