| Summary | 0001166: Using $this in __debugInfo() causes infinite recursion (Doesn't appear to be the same as issue 0001140) | ||||
| Description | When debugging with Xdebug 2.3.3 on PHP 5.6.9, stepping into an object that has a defined __debugInfo() method that refers to $this causes an uncaught LogicException; 'The object is in an invalid state as the parent constructor was not called' When single-stepping, the moment the first expression in the constructor is stepped into, execution skips to the __debugInfo() method, where it dies upon encountering $this. | ||||
| Steps To Reproduce | php -dxdebug.auto_trace=1 -dxdebug.collect_params=3 -r 'class Foo extends IteratorIterator{function __construct($items){if(is_array($items)){$items=new ArrayIterator($items);}}function __debugInfo(){return ["count"=>iterator_count($this)];}};$a=new Foo([1,2,3]);var_dump($a);' | ||||
