Hi!

I've noticed that this buggy code causes a windows xp crash and reboot:

*******
class A {
 var Object;
 function A(){
  $this->Object = new B();
 }
}

class B {
 var Object;

 function B(){
  $this->Object = new A();
 }
}

****
and then running:

$myObject = new B();

***********************

I figure that first of all this should not result in that windows reboots. Second I wouldn't mind if with the notices turned on it should report a notice for this error (I can't be the only one that's done this). At least there should be such a check for the constructor since it seems that I can't learn from my previous mistakes :-D

Thanks for great software!

PS. I'm running latest version of apache 2 DS

Check your hardware for stability. PHP cannot possibly cause windows to reboot without either a major kernel bug in windows or faulty hardware.

I've been thinking about reinstalling win xp for some time now but I hate reinstalling all my software and reconfiguring. I know that there is something fishy with my xp but this is the only time it actually reboots. That's why I still think it may be an issue that may be interesting to fix.

What happens is a stack overflow due to an unterminated loop. PHP has no internal stack protection so it crashes. As to why windows crashes & reboots that's already an MS bug and not a PHP problem. 
In a properly working OS, this would only result in a PHP crash.
