Description:
------------
Hi,

I am compiling pecl-gearman 1.1.2 against gearmand 1.1.16 and I am running into a very strange issue.  Everything appears to be compiling and working except for a couple of functions on GearmanWorker class.  

PHP Warning:  GearmanWorker::addServers(): (null) in ...

PHP Warning:  GearmanWorker::addFunction(): Unable to add function to Gearman Worker: (null) GEARMAN_INVALID_ARGUMENT in ...

This appears to be a problem when talking from the PHP extension to libgearman. The php extension is definitely getting called with the correct values ("127.0.0.1" and 4730) @ https://github.com/hjr3/pecl-gearman/blob/gearman-1.0/php_gearman.c#L3311 but obj->ret == GEARMAN_INVALID_ARGUMENT when I debug.  The only way that should happen is that &(obj->worker) == NULL on libgearman's end, but &(obj->worker) definitely looks like a pointer from the PHP extension end. I am not sure whats happening...

I have also tested the same gearmand libgearman version against 2.x (hjr3/pecl-gearman) and I am having the same problem.

Ok, under normal circumstances this works fine.  It seems to soil the pants only if the GearmanWorker class is a member variable of a class that extends Stackable!  I.E. `
```
class MyWorker extends Stackable {
    /** @var GearmanWorker $gearman */
    protected $gearman;

    public function __construct()
    {
        $this->gearman = new GearmanWorker();

        // Poops pants here.
        $this->gearman->addServer("127.0.0.1", 4730);
    }

    ...
}
```

The gearman package have not had a release since 2013 and no development since, its safe to say that this package is no longer maintained, if development picks back up then this report should be re-opened
