Bug #77955 [Com]: Random segmentation fault in mysqlnd from php-fpm

Edit report at https://bugs.php.net/bug.php?id=77955&edit=1 ID: 77955 Comment by: victoria at sharksmedia dot dk Reported by: victoria at sharksmedia dot dk Summary: Random segmentation fault in mysqlnd from php-fpm Status: Closed Type: Bug Package: PDO MySQL Operating System: CentOS 7.6.1810 PHP Version: 7.3.4 Assigned To: dmitry Block user comment: N Private report: N New Comment: Hi, I'm just writing to confirm that the segmentation fault is gone with php 7.3.7. But there seem to be massive memory leaks still present, i'm still getting the "Allowed memory size of x bytes exhausted", very quickly in longer running scripts such as cronjobs. I'm isolating the problem, and posting a new bug. Thanks for fixing this one though :) Previous Comments: ------------------------------------------------------------------------ [2019-06-03 07:56:07] scott at exussum dot co dot uk Hi Dmitry / Nikita That fix has changed something we now get terminated by signal SIGSEGV (Address boundary error) It terminates at a similar place though. Anything I can do to help debug this further ? ------------------------------------------------------------------------ [2019-06-03 07:16:10] dmitry@php.net The fixes are going to stay in all versions. Confirmation is not necessary. If you'll see the problem - reopen the bug report. It's not possible to run different PHP components, built in different "debug" mode. ------------------------------------------------------------------------ [2019-06-03 06:02:36] victoria at sharksmedia dot dk Hi Dmitry I see the fixes weren't inclded in 7.3.6. Will they be in 7.3.7, or do you need to have confirmation of it working before it is included in the release? As mentioned, i can't "just" run a debug build, as remi doesn't provide it and wont help make one. Can i compile a debug version of the php binary, and mysqlnd.so, and use that with all the extensions not compiled in debug mode? Or must ALL loaded binaries be compiled in the same debug mode? Because, than i can just compile php, and replace the two binaries on the production server without messing more with the production setup. ------------------------------------------------------------------------ [2019-05-24 05:24:42] victoria at sharksmedia dot dk That looks good. Will this fix be in 7.3.6? Since we're using the remi repo, it is quite a task to compile it all to be a direct swapable replacement (Remi couldn't provide info on how to compile his SRPMS) ------------------------------------------------------------------------ [2019-05-23 15:12:05] dmitry@php.net Most probably, the bug is fixed by https://github.com/php/php-src/commit/6f9dfd947302f9a0d2fa6a78bf385b1ca7dafdf3 Victoria, it would be great if you could test your app, using DEBUG build of PHP-7.3 snapshot. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
