Hello,

I discovered this problem tonight while working on a new PHP 5 class that 
uses an interface.  The code example came from 
http://www.zend.com/php5/articles/engine2-php5-changes.php#Heading5


<?php
    interface Throwable {
       public function getMessage();
    }

    class MyException implements Throwable {
       public function getMessage() {
           echo "Hello\n";
       }
    }

    $x = new MyException;
    $x->getMessage();
?>

------------------

On this server, I get a Segmentation Fault:

[ionzoft@lithium dev]$ php -v
PHP 5.0.0RC3 (cli) (built: Jun 24 2004 17:35:13)
Copyright (c) 1997-2004 The PHP Group

     with Zend Debugger v3.5.0, Copyright (c) 1999-2004, by Zend Technologies

[ionzoft@lithium dev]$ php -f Interface.php
Segmentation fault

------------------

On this server, It works fine:

[izsp@boron Jason]$ php -v
PHP 5.0.0RC3 (cli) (built: Jun 14 2004 14:04:10)

[izsp@boron Jason]$ php -f Interface.php
Hello

------------------

Could it be a problem with the Debugger?

Thanks,
Jason Garber

We'll look into it and let you know whether it's in PHP or in one of the 
extensions modules.

Thanks for the report!
