Please try using this CVS snapshot:
http://snaps.php.net/php5-STABLE-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php5.0-win32-latest.zip
I can't reproduce it with latest 5.0.x-CVS version.

Description:
------------
If class B's constructor is defined as __construct(A $anObject),
calling new B(new A) without taking the return value causes a crash
(SIGBUS).
Not using type hinting or assigning the result to a variable seems to
work around the problem.
E.g. $tmp = new B(new A()) does not produce the crash.
Reproduce code:
---------------
<?php
Class A {
function __construct(){}
}
Class B {
function __construct(A $a){}
}
new B(new A());
echo 'OK';
?>
Expected result:
----------------
A simple OK would be nice ;)
Actual result:
--------------
Program terminated with signal 10, Bus error.
