Edit report at https://bugs.php.net/bug.php?id=69233&edit=1 ID: 69233 Comment by: phpbugs at e-milt dot net Reported by: julientld at free dot fr Summary: PHP-CGI.EXE and OPCache crash with error code 0xc0000005 Status: Open Type: Bug Package: opcache Operating System: Windows Server 2012 PHP Version: 7.0.1 Block user comment: N Private report: N New Comment: Any update on this? I've seen reports about this going back a few years already and this error is still happening event with the current 7.0.14 version. It's very unpredictable, sometimes it happens but not all of the time. I don't think it depends on the script being executed. It seems to happend during startup of the PHP process itself.

FYI, I have set the opcache.file_cache option. Not tried without. Need more time to affirm definitely that the bug is 100 % fixed. ------------------------------------------------------------------------ [2015-05-14 15:59:14] quantuumsnot at gmail dot com The exact error: Unhandled exception at 0x000007FEEDE981BC (php_opcache.dll) in php-cgi.exe: 0xC0000094: Integer division by zero. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
