[BUG] SEGFAULT with Phalcon 1.3.1 and Xdebug

[vladimmi]

Have a SEGFAULT with a Xdebug and Phalcon 1.3 after release (including just compiled 1.3.1) - previous versions seems to haven't this problem.

Some collected info:

• Arch Linux x64 with 3.13.7 kernel
• Apache 2.4.9
• PHP 5.5.10 NTS
• Zend Engine 2.5.0
• Zend OPcache 7.0.3
• Xdebug 2.2.4
• Phalcon 1.3.1 compiled from master

Tried to collect some information from coredump, bt full - https://gist.github.com/vladimmi/9787642

Looks like, SEGFAULT goes from this part of code:

//$di = new Phalcon\DI\FactoryDefault();
$viewEngines = array(
    ".volt" => function($view, $di) {
        $volt = new \Phalcon\Mvc\View\Engine\Volt($view, $di);
        $volt->setOptions(array(
            'compiledPath' => PATH_APP_CACHE . 'views/',
            'compiledSeparator' => '_',
            'stat' => false,
            'compileAlways' => true
        ));

        //register functions...
        //register filters...

        return $volt;
    }
);

//Volt
$di->set('view', function() use($viewEngines) {
    $view = new \Phalcon\Mvc\View();
    $view->setViewsDir(PATH_APP_VIEWS);
    $view->registerEngines($viewEngines);
    return $view;
});

...just after "return $volt;". At least, step-by-step debug brakes at this point.

If any additional info needed - let me know, I'll try to gather it.

I think this bug caused in xdebug
can you build package with

phpize && ./configure CFLAGS="-O2 -g" && make clean && make -B && sudo make install && service php5-fpm restart

and php recompile with +debug option after it and i think the best soulition create bug in xdebug project with full log ^_^

this project can help you to easy compile the php env with debug option

Looks like Arch makepkg configuration already has "-g" for "debug" option. I've manually recompiled packages with "debug" option before making coredumps, so, as I understand, PHP, Xdebug and Phalcon are already built with this flags.

Any more info need here or I can start searching Xdebug bug tracker to post it there? :) And what full log do you mean?

Added a pull request on xdebug to fix the problem: xdebug/xdebug#120

[vladimmi]

PR is not merged for a 15 days without any activity - maybe you have to collaborate with xdebug developers in some way?

[phalcon]

Fixed in Xdebug 2.2.6
