Edit report at https://bugs.php.net/bug.php?id=68252&edit=1 ID: 68252 Comment by: bugs at milos dot nz Reported by: bugs at milos dot nz Summary: segfault in Zend/zend_hash.c in function _zend_hash_del_el Status: Open Type: Bug Package: Reproducible crash Operating System: Linux 3.16 (Gentoo) PHP Version: master-Git-2014-10-17 (Git) Block user comment: N Private report: N New Comment: I have been able to replicate this on an isolated system with one of the affected WordPress installs. The issue seems to be directly related to opcache being loaded. With 'zend_extension=opcache.so' commented out in php.ini, the segmentation fault no longer occurs. For the record, the php.ini file was the same as that recommended on the official PHP wiki (https://wiki.php.net/phpng): max_execution_time=600 memory_limit=128M error_reporting=E_ALL & ~E_NOTICE display_errors=1 log_errors=1 user_ini.filename= realpath_cache_size=2M cgi.check_shebang_line=0 upload_max_filesize = 1024M post_max_size = 1024M zend_extension=opcache.so opcache.enable_cli=1 opcache.save_comments=0 opcache.fast_shutdown=1 opcache.validate_timestamps=1 opcache.revalidate_freq=60 opcache.use_cwd=1 opcache.max_accelerated_files=100000 opcache.max_wasted_percentage=5 opcache.memory_consumption=128 opcache.consistency_checks=0 I have e-mailed you root access to an isolated virtual machine containing the WordPress install that exhibits this bug.
