Edit report at https://bugs.php.net/bug.php?id=80422&edit=1 ID: 80422 Updated by: dmitry@php.net Reported by: martin at radiok2r dot de Summary: php_opcache.dll crashes when using Apache 2.4 with JIT -Status: Assigned +Status: Closed Type: Bug Package: JIT Operating System: Windows 10 64-bit PHP Version: 8.0.0 Assigned To: dmitry Block user comment: N Private report: N New Comment: Automatic comment on behalf of dmitry@zend.com Revision: http://git.php.net/?p=php-src.git;a=commit;h=3edf5c969a9f5f3290852ab9edf61a876fca63d0 Log: Fixed bug #80422 (php_opcache.dll crashes when using Apache 2.4 with JIT) Previous Comments: ------------------------------------------------------------------------ [2021-01-13 08:11:11] martin at radiok2r dot de I changed the code for testing a bit to make it independent from the webserver: <?php print "Hello world\r\n"; for ($i = 0; $i < 100; $i++) { $b = file_exists("index.php"); print $i; var_dump($b); } print "It worked"; This code still crashes in Apache, but works fine with CLI. I'm not sure what else I could do to make it reproducible for you, I already gave you the versions from Apache I'm using. What else could influence that it works for you and not for me and louisowen? ------------------------------------------------------------------------ [2021-01-13 06:12:39] dmitry@php.net I wasn't able to reproduce the crash on test case from @martin. Is it crashes on very first request (after web server start)? I need a well reproducible test case to analyse and fix this. Better, if it possible to reproduce the crash with CLI PHP (without Apache). However, the problem may be especially related to Apache SAPI (ZTS or Windows ASLR). ------------------------------------------------------------------------ [2021-01-13 02:30:15] louisowen at me dot com same situation,hope this bug can be solved quickly. ------------------------------------------------------------------------ [2020-12-14 15:49:47] martin at radiok2r dot de Thanks for your reply and all your hints! It all works with opcache.jit=1205 without problems. Without opcache.jit=1205 (no setting for opcache.jit at all in the php.ini) this php-code crashes: <?php print "Hello world\r\n"; print $_SERVER["DOCUMENT_ROOT"]."\r\n"; for ($i = 0; $i < 100; $i++) { $b = file_exists($_SERVER["DOCUMENT_ROOT"]."/index.php"); } print "It worked"; When reducing the loop to run 50 times it works, but 100 times is too much and it crashes. Hope this helps. ------------------------------------------------------------------------ [2020-12-14 13:42:57] dmitry@php.net Also try to reproduce the same problem with opcache.jit=1205. If you see the same crash, try to isolate the problem with opcache.jit=1205 (it should be easier). ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
