Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read

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'.
Program terminated with signal 11, Segmentation fault.
