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. ------------------------------------------------------------------------ [2014-10-22 08:58:53] laruence@php.net great, thanks, a temporary access is enough :) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
