Description:
------------
When assigning the result of MySQLi_connect() to a variable crashes PHP.
while just calling MySQLi_connect() with the same arguments doesn't crash.

I run Apache 2.0.49 Win32 on Windows XP with the Latest PHP5 CVS version.

PHP.ini diff:
zend.ze1_compatibility_mode = On
allow_call_time_pass_reference = Off
error_reporting  =  E_ALL
register_argc_argv = Off
extension_dir = "C:\php\ext\"
extension=php_mysqli.dll
mysqli.default_host = barserver


Reproduce code:
---------------
<?php
//this is good:
mysqli_connect("barserver","baruser","barpass");
// This crashes
$foo = mysqli_connect("barserver","baruser","barpass");
?>

<?php
// when disabeling mysqli and enableing mysql extension
// this is good:
$foo = mysql_connect("barserver","baruser","barpass");
?>

Expected result:
----------------
I expected that $foo would be assigned a mysqli link or mysqli object.

Actual result:
--------------
Apache + PHP crashes
