Hiya,

Using the same var from the function and changing will sefault, copying it first to another var will work... but should not happen, see examples
<?
	ob_start('Segfault_Me');

	// works
	function Segfault_Me ($data) {
		$data2 = $data . "I didn't segfault :) :) :)";
		return($data2);
	}

	// segfaults
	function Segfault_Me ($data) {
		$data = "I didn't segfault :) :) :)";
		return($data);
	}

	// segfaults 2
	function Segfault_Me ($data) {
		$data = str_replace('a', 'b', $data);
		return($data);
	}
?>
I segfaulted :( :( :(

Greetz,

Wico de Leeuw

Fixed typo;

Btw where did the bug reporters stats go? It looks good to be on top ;)

Does this problem still occur with 4.1.1 and/or the latest CVS?
 [2002-01-06 09:26 UTC] wico at cnh dot nl 
yup still segfaults with 4.1.0
 [2002-01-06 16:54 UTC] wico at cnh dot nl 
also true for 4.1.1

Assign to me so that I don't forget about this.
Zeev may want to fix this, though :)

This bug has been fixed in CVS. You can grab a snapshot of the
CVS version at http://snaps.php.net/. In case this was a documentation 
problem, the fix will show up soon at http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites.
Thank you for the report, and for helping us make PHP better.
