The below script causes a segmentation fault when the commented out line in the second class is uncommented. There is no crash when the default value "true" is replaced with a string or a number. It seems the problem occurs when a Boolean, true or false, is the default value for the constructor of the first class "param".

<?php
//	require("parm.h");



	class param {
		var	$parm;
		
		function param($inParm = true) {
			$this->parm = $inParm;
		}
		
	}

	class parmAddrTelephone extends param {
		var	$area;

		function parmAddrTelephone() {
//	Uncomment the line below
//			$this->area = new param();
		}
	}
	echo "<BR>Version 25.";

	echo "<BR>Done.";
?>
