    public function authUser($attribute = null)
{
    return reset($this['events']->fire('auth.user', $attribute)); //line 552
}

You'll probably find that reset() is defined as something like...

reset( &$value ) {}

Which is expecting the value to be passed by reference. When you call this, you need to pass an actual variable as opposed to directly passing in the return value from a function. So...

public function authUser($attribute = null)
{
    $value = $this['events']->fire('auth.user', $attribute);
    return reset($value); //line 552
}

public function adminCheck()
{
    $value = $this['events']->fire('admin.check');
    return reset($value) === true; //line 563
}

This could also be a result of fire() being declared in a similar manner, you need to work out which one is causing the problem and amend as above.
