stack overflow in JIT

Comienza reproduciendo el stack overflow con el programa PHP y el comando JIT proporcionados. Lee Zend/zend_objects.c alrededor de la línea 77 y Zend/zend_objects_API.c alrededor de la línea 193, donde se repite el sanitizer trace. El trabajo estará terminado cuando el reproducer ya no aborte con un stack overflow y el comportamiento de destrucción de objetos esté cubierto por una prueba de regresión.

Description

The following code:

<?php
class N { public $n; }
$o=null;
for($i=0;$i<1000000;$i++){ $x=new N; $x->n=$o; $o=$x; }
$o=null;
