Description:
------------
With PHP v. 5.0.0b2 on Win98 SE installed under Apache 1.3.22 as CGI an attempt to call an unexisting class variable inside foreach construct produces crash instead of error (possibly fatal).
Problem exist only when call is executed inside class declaration. Attempt to do this outside class declaration produces expected Warning: Invalid argument supplied for foreach() and Fatal error: Cannot redeclare class 


Reproduce code:
---------------
<?php 
class Test {
	var $a=array(1,2,3,4);
	function __construct() {
		foreach($this->b as $row) {
			if($row=='foo') {
				return true;
			}
		}
	}
} 


Expected result:
----------------
Warning: Invalid argument supplied for foreach() in <file> on line <line>

Fatal error: Cannot redeclare class test in <file> on line <line>


Actual result:
--------------
a crash

from Apache log:
[error] [client 127.0.0.1] Premature end of script headers: c:/php/php.exe
