Bug #74008 [Opn->Fbk]: Segmentation fault using Drupal 7

Edit report at https://bugs.php.net/bug.php?id=74008&edit=1 ID: 74008 Updated by: dmitry@php.net Reported by: pierre at brin-de-toile dot fr Summary: Segmentation fault using Drupal 7 -Status: Open +Status: Feedback Type: Bug Package: Reproducible crash Operating System: Debian Jessie 64 bits PHP Version: 7.0.15 Block user comment: N Private report: N New Comment: It looks like this problem caused by use-after-free or double-free. It would be great to catch the original source of the problem using valgrind. Instead of php-fpm, run single process FastCGI server under valgrind and perform few requests that caused crash (they are going to be served very slow). $ USE_ZEND_ALLOC=0 valgrind php-cgi -b <listen-socket> Previous Comments: ------------------------------------------------------------------------ [2017-04-18 17:06:07] kol at nextmail dot ru Same issue.
