New Comment:
You're recursively calling the constructer without end condition so the
stack overflows. As per previous discussions we will not make a defence
against this.

The following code segfaults.
class Class2 extends Class1
{
}
class Class1
{
function Class2(){
return new Class2;
}
}
Class1::Class2();
I don't actually know if it's valid PHP code or not, but I don't think
it should segfault either way.
Conditions:
It only happens if Class2 extends Class1.
It only happens if Class2 does not have a constructor.
Confirmed with 4.2.2 and 4.3.0RC1 on Slackware 8.1, 2.4.19 and 4.2.3 on
FreeBSD 4.4-RELEASE.
Configure line: './configure' '--with-mysql'
'--with-apxs=/usr/sbin/apxs'
I've never done a backtrace before, and I'm not sure I did it right,
but hopefully this is of some use to someone... :)
