Description:
------------
Every try to connect to the MySQL Server ends up in a segmentation fault.
When using the Apache2 Module I get the following log-output:
[notice] child pid 25103 exit signal Segmentation fault (11)

Using cli/php i just get "Segmentation fault" - without being any more specific...

This problem occours with:
php-5.0.0b1
php-cvs2003-08-31
php-cvs2003-09-06

Apache 2.0.47
MySQL 4.0.14

./configure 
  --prefix=/usr/local  \
  --exec-prefix=/usr/local  \
  --bindir=/usr/local/bin  \
  --sbindir=/usr/local/sbin  \
  --libexecdir=/usr/local/libexec  \

  --with-mysql=/usr/local \
  --with-mysql-sock=/tmp/mysql.sock  \

MySQL Configure Options:
./configure \
  --prefix=/usr/local \
  --enable-dependency-tracking \
  --localstatedir=/home/mysql \
  --enable-assembler \
  --with-unix-socket-path=/tmp/mysql.sock \
  --with-mysqld-user=mysql \
  --with-mysqld-ldflags=-all-static



I hope I provided all necessary information and that this isn't a bug but my fault... :)


Reproduce code:
---------------
<?php
echo 'Trying to connect ... ';
$con = mysql_connect('localhost','user','pass') or die ("Unable to connect ...");
echo "super!";
mysql_close($con);
?>


Expected result:
----------------
super!

Actual result:
--------------
