From: Operating system: linux PHP version: 5.3.6 Package: MySQLi related Bug Type: Bug Bug description:segmentation fault
Description: ------------ I observe a segfault when running a xenforo package in debug mode. The configuration of the server is Fedora Core 8, MySQL 5.0.45 I recompiled PHP with debug mode and turned off all extensions not from the standard archive. I found a way to avoid it by recompiling the mysqli extension with mysqlnd driver. I am not really sure if it was worth to open this report as I don't know how you can reproduce it, but at least you'll hear about the issue. Test script: --------------- I am not sure I can make a minimal reproducable case. Xenforo is a large package based on Zend Framework. any call to the xenforo scripts in debug mode crashes php, both fcgi and cli Actual result: -------------- backtrace: Core was generated by `php index.php'.
