Glad to hear mysqlnd works fine.
Its impossible to tell what could be going on with libmysql by just
checking the backtrace. You seem to be using an older version of
MySQL/libmysql. Could you try a recent version of libmysql?
Also, as hard as it is, it would be most helpful to get a reproducible
test script.

Sorry, I meant backtrace.
Or you need some other one?
[2011-05-01 21:06:41] public at grik dot net
I am sorry, but the bugtrace is already posted in the report.

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
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to Open. Thank you for helping
us make PHP better.

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.
