Hi all!
This small script:
<?
class test {
var $a = false;
var $x = false;
function getA() {
if (!$this->x) { // yep, I know, it's infinite loop
$this->foo();
}
return $this->a;
}
function foo() {
return $this->getA();
}
}
$test = new test;
$test->getA();
?>
produces segfault in latest HEAD.
A small part of backtrace(it's really huge) is below:
Program received signal SIGSEGV, Segmentation fault.

Hi all!
This small script:
<?class test {
var $a = false;
var $x = false;function getA() {
if (!$this->x) { // yep, I know, it's infinite loop
PHP always crashes on infinite loops as you might be aware off. You'll
have to live with it.

And there is no workarounds at all?
(BTW, same results with PHP_4_3..)

Just don't make infinite loops? :)

php5 shouldn't crash at all within an infinite loop because we aren't
in one big execution loop.

Why shouldn't this crash eventually? You still have to account for all
the callers stacks.
