Subject: Re: [PHP-DEV] Destructors will not be called after an exception is caught?
From: helly@php.net (Marcus Boerger)

Hello Noel,

i suppose one of your destructors did throw an exception. But you didn't
get any output from it. Try either 5.0.0-dev or 5.1.0-dev where the
shutdown order wasaddressed again. A reproducing script would be this:

php -r 'class t{function __destruct(){throw new exception(__METHOD__);}}$o=new t;'

regards
