Edit report at https://bugs.php.net/bug.php?id=78894&edit=1 ID: 78894 Comment by: luis dot armengol at koyi dot tv Reported by: luis dot armengol at koyi dot tv Summary: Preload: double free or corruption crash Status: Feedback Type: Bug Package: opcache Operating System: Centos 7.3 PHP Version: 7.4.0 Block user comment: N Private report: N New Comment: Still crashing in 7.4.1 RC1 I can prepare a very basic web application with ZF1 if you need it and send you wherever you want. Meanwhile, this is a small preload file content im using that its working. If you uncomment the block of Zend/Db classes it will crash when trying to load the site (when executing bootstrap) (at least in my case) -------------------------------- <?php set_include_path(get_include_path() .

We've fixed quite a few preloading bugs in the last week, would be great if you could recheck whether things are working now. ------------------------------------------------------------------------ [2019-12-15 04:22:08] php-bugs at lists dot php dot net No feedback was provided.

Context: php-fpm running on a ubuntu based container When trying to test our codebase against php7.4 with preloading enabled we get exactly the same problem. Our preload file basically contains an include_once 'vendor/autoload.php' and then a series of require_once some_files.php` which require all the classes that we use from a proprietary framework. There is nothing much special done there and the requires are around 210. ------------------------------------------------------------------------ [2019-12-04 09:07:41] nikic@php.net Can you please provide the script you use for preloading? ------------------------------------------------------------------------ [2019-12-01 01:04:27] luis dot armengol at koyi dot tv Description: ------------ Im trying to preload all ZF1 classes to opcache without any luck. Im preloading classes by block manually, I mean, all Zend/Db, all Zend/Cache, all Zend/Config and it works perfectly until a number of require_once or opcache_compile_file calls. It starts perfectly httpd service without any error but in the first http call I receive a crash with Error in `/usr/sbin/httpd': double free or corruption. Also I receive that crash/segmentation fault in those cases when I shutdown httpd service. If I disable the preloading of one of the block classes (ie: Zend/Db) I can preload another block and it works, so I assume is something about the number of files of ZF1 im trying to preload (i know its old but without preloading its working ok) Actual result: -------------- *** Error in `/usr/sbin/httpd': double free or corruption (!prev): 0x0000556c4e770c30 *** ======= Backtrace: ========= /lib64/libc.so.6(+0x81679)[0x7f307c037679] /etc/httpd/modules/libphp74.so(+0x300f34)[0x7f306db05f34] /etc/httpd/modules/libphp74.so(zend_hash_add+0x121)[0x7f306db06091] /etc/httpd/modules/libphp74.so(+0x2e2159)[0x7f306dae7159] /etc/httpd/modules/libphp74.so(+0x2e2aa7)[0x7f306dae7aa7] /etc/httpd/modules/libphp74.so(+0x2e2ad0)[0x7f306dae7ad0] /etc/httpd/modules/libphp74.so(+0x2ba0b5)[0x7f306dabf0b5] /etc/httpd/modules/libphp74.so(compile_file+0x8a)[0x7f306dac07fa] /opt/remi/php74/root/usr/lib64/php/modules/opcache.so(+0x14b11)[0x7f306cb86b11] /opt/remi/php74/root/usr/lib64/php/modules/opcache.so(+0x17747)[0x7f306cb89747] /etc/httpd/modules/libphp74.so(+0x33eb1d)[0x7f306db43b1d] /etc/httpd/modules/libphp74.so(+0x35aa80)[0x7f306db5fa80] /etc/httpd/modules/libphp74.so(execute_ex+0x18b2)[0x7f306db78162] /etc/httpd/modules/libphp74.so(zend_execute+0x131)[0x7f306db7f461] /etc/httpd/modules/libphp74.so(zend_execute_scripts+0xc3)[0x7f306daf9563] /etc/httpd/modules/libphp74.so(php_execute_script+0x270)[0x7f306da98430] /etc/httpd/modules/libphp74.so(+0x37c1e0)[0x7f306db811e0] /usr/sbin/httpd(ap_run_handler+0x40)[0x556c4d8ddaf0] /usr/sbin/httpd(ap_invoke_handler+0x69)[0x556c4d8de039] /usr/sbin/httpd(ap_internal_redirect+0x4c)[0x556c4d8f1fac] /etc/httpd/modules/mod_rewrite.so(+0x4e4c)[0x7f30762b1e4c] /usr/sbin/httpd(ap_run_handler+0x40)[0x556c4d8ddaf0] /usr/sbin/httpd(ap_invoke_handler+0x69)[0x556c4d8de039] /usr/sbin/httpd(ap_process_async_request+0x1ea)[0x556c4d8f2c4a] /usr/sbin/httpd(ap_process_request+0x22)[0x556c4d8f2f32] /usr/sbin/httpd(+0x530c2)[0x556c4d8ef0c2] /usr/sbin/httpd(ap_run_process_connection+0x40)[0x556c4d8e7120] /etc/httpd/modules/mod_mpm_prefork.so(+0x37af)[0x7f30736fb7af] /etc/httpd/modules/mod_mpm_prefork.so(+0x39f5)[0x7f30736fb9f5] /etc/httpd/modules/mod_mpm_prefork.so(+0x468e)[0x7f30736fc68e] /usr/sbin/httpd(ap_run_mpm+0x4e)[0x556c4d8c20ce] /usr/sbin/httpd(main+0xa96)[0x556c4d8bae26] /lib64/libc.so.6(__libc_start_main+0xf5)[0x7f307bfd8505] /usr/sbin/httpd(+0x1ef5f)[0x556c4d8baf5f] ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78894&edit=1
