Description:
------------
i try to compile php 5.2.3, 5.2.5 and 5.2.6rc5

my configure:
./configure \
--prefix=/usr/php --sysconfdir=/etc/php5/apache2 --mandir=/usr/share/man \
--with-apxs2=/usr/sbin/apxs \
--libexecdir=/usr/lib/php5 --bindir=/usr/bin --libdir=/usr/lib/php5 \

This sentence work in debian lenny and fedora core with mysql 5.1 (32bits)

my system:
Debian Etch (amd64)
mySQL 5.1

But any application fails with a segmentation fault.

It's not a problem with php5 classes, because wordpress 2.3 and joomla 1.4 also fail.

when i remove --with-mysqli, failures do not occur

Reproduce code:
---------------
Any code with mysql/mysqli crash with this error:
[notice] child pid 20330 exit signal Segmentation fault (11)

optional, this error appears with --enable-debug:
zend_mm_heap corrupted

Run Wordpress, Joomla or any database application with mysql/mysqli.

Actual result:
--------------
In Debian Etch (64bits) any application that use mysql/mysqli crash with this error:
zend_mm_heap corrupted
and a signal segmentation fault (11)
[notice] child pid 20330 exit signal Segmentation fault (11)

with --enable-debug; dmesg returns:
