Edit report at https://bugs.php.net/bug.php?id=77260&edit=1 ID: 77260 Comment by: erik at coretech dot se Reported by: ettore at themecraft dot studio Summary: preg_match_all(): JIT compilation failed: no more memory Status: Open Type: Bug Package: PCRE related Operating System: macOS 10.13.6 PHP Version: 7.3.0 Block user comment: N Private report: N New Comment: This is probably not a bug but selinux blocking php from fiddling with executable stacks. This is probably a bad idea to enable on a hardened system and should be disabled within php.ini (pcre.jit=0) To check if this generated a selinux warning use: aureport --avc 1. 06/19/2019 07:17:05 httpd system_u:system_r:httpd_t:s0 9 process execmem system_u:system_r:httpd_t:s0 denied 240395 If you still want to enable this, use: setsebool -P httpd_execmem on /Erik Lundin Previous Comments: ------------------------------------------------------------------------ [2019-05-13 07:44:11] mathieu dot ferment at prestashop dot com Same issue when trying to run composer install on prestashop project (ithub.com/PrestaShop/PrestaShop/). php7.3 installed using homebrew $ /usr/local/Cellar/php/7.3.5/bin/php composer.phar install PHP Fatal error: Uncaught ErrorException: preg_match_all(): JIT compilation failed: no more memory in phar:///Users/mFerment/www/prestashop/PrestaShop/composer.phar/vendor/symfony/console/Formatter/OutputFormatter.php:137 Worked around it by switching pcre.jit from 1 to 0.

Until this is dealt with in the upstream. I suggest set in php.ini pcre.jit=0 ------------------------------------------------------------------------ [2019-03-01 20:22:23] veraxcloud at gmail dot com Here same problem with centos 7 and PHP 7.3.2 FPM. First noticed on "Wordpresss W3 Total Cache" with the minifying process but also on other Projects seen. Disabling JIT compilation solved the problem also here. :) ------------------------------------------------------------------------ [2019-02-18 06:42:09] gerwinkrist at gmail dot com On RHEL 7 we also have the problem, so it's not Mac specific. To be more specific we have it with 7.3 and Laravel. ------------------------------------------------------------------------ [2019-02-04 09:38:35] marek dot svent at gmail dot com I do – on Linux, but in crosscompiled environment.
