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.
