Oh, I forgot the gtk versions, dpkg reports

Ubuntu 10.04: 2.20.1-0ubuntu2.1
Ubuntu 12.04: 2.24.10-0ubuntu6 & 3.4.2-0ubuntu0.4

I can reproduce this on clean installations of Ubuntu 10.04 & 12.04 with the following procedures (slight changes due to package name changes etc)

Ubuntu 10.04: http://pastebin.com/vHuHDc3R
Ubuntu 12.04: http://pastebin.com/gB0LRAkE

Thank you for your interest in PHP.


I can't reproduce this with the current version in git on 5.3 or 5.4

Can you try a newer compile of php-gtk?  Also what gtk library version are you using, and are you using Ubuntu distro builds of php - if so please try with a stock build of PHP

Description:
------------
The first time the OK button on the dialog is clicked the custom signal is emitted correctly, on the second click php segfaults on the call to emit().

If no object is provided to emit() the second signal emits without segfault as expected.

Test script:
---------------
<?php

/**	Class implements custom signal 'product-ready'. */
	class customDialog extends GtkDialog {
	    public $__gsignals	= array(
            		'product-ready'  => array(
	    				GObject::SIGNAL_RUN_LAST,
	    				GObject::TYPE_BOOLEAN,
	    				array(
	    					GObject::TYPE_PHP_VALUE
	    				)
	    			)
				);

		public function __construct($title, GtkWindow $parent) {
			parent::__construct($title, $parent, Gtk::DIALOG_MODAL);

			$product	= new stdClass();

			$okButton	= new GtkButton('OK');
			$this->action_area->add($okButton);
			$okButton->connect_simple('clicked', array($this, 'ok_clicked'), $product);
		}

		public function ok_clicked(stdClass $product) {
			$this->emit('product-ready', $product);
		}
	}
	GObject::register_type('customDialog');



	$window	= new GtkWindow();
	$window->show_all();

	$dialog	= new customDialog('fire signal dialog', $window);
	$dialog->show_all();

	$dialog->connect('product-ready', 'product_ready');

	function product_ready() {
		echo 'segfaults on second signal' . "\n";
		return true;
	}

	Gtk::main();
