Edit report at https://bugs.php.net/bug.php?id=78592&edit=1 ID: 78592 Updated by: requinix@php.net Reported by: john dot royer at gmail dot com Summary: filter related extension cause Segmentation fault -Status: Feedback +Status: Open Type: Bug -Package: Filter related +Package: JSON related Operating System: Linux (Ubuntu 18.04) PHP Version: 7.3.9 Block user comment: N Private report: N New Comment: > Is it means PHP crashed while using JSON extension ? More or less. The issue could be with json_decode(), or it could be with the engine internals that the function was using. What if you phpbrew install with filter and without json? Or with json and without filter?

Run by vendor/bin/phpunit ... PHPUnit 7.5.15 by Sebastian Bergmann and contributors. ............................................................Segmentation fault (core dumped) //------------------------------- Sorry, issue cause only run after a lot of tests. If I just run patial test, like phpunit test/src/ApplicationTest.php, there is no error occur. My PHP environment is as the gist shown: https://gist.github.com/johnroyer/1c05332c94db0374ffc0d823fee0818b. Hope this helps. Test script: --------------- I use phpbrew to rebuild PHP 7.3.9 and add extension step by step. Issue occurs after a compile filter library : phpbrew install 7.3.9 +cli +json +pdo +xml +curl +mysql +hash +ctype +openssl +filter Expected result: ---------------- PHPUnit should run all the test and should not have any PHP language related issue. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78592&edit=1
