@cataphract, why was this re-opened?
AFAICT there won't be a recursion counter.

C lets you do a lot of stuff you aren't supposed to do. Just because C allows it
doesn't mean higher level languages like PHP should. An out of memory error is
much more helpful than a segfault, which could come from anything. Also, segfaults
have historically lead to exploits.

This segmentation fault / coredump behavior is consistent with what lower level
languages like C. So IMHO this should not be considered a PHP bug. Just don't get
into infinite recursions. The language can't stop you from doing something stupid.
Here's a C program that demos the same behavior:
------------------------------
#include<stdio.h>
void fn() {
char buff[16*1024];
fn();
}
int main(void) {
fn();
}

$ php a.php
a before cloning:
a: [- >]
Segmentation fault

And what do you get when you try with the reproduce code?
