why don't I get the "stack overflow" error?
or any error at all?

I just think the blank page is not the best way to reflect errors :-)

I do not claim the :: and -> are thre same.
The bug is the segfault.
Could you please be more careful?

And for the record, you're nesting many levels of function calls, which
exhaust the stack. That's why you get a segfault - the only case where
it is acceptable in PHP.

:: and -> are not equivalent operators, please read the manual. This is
not a bug.

Description:
------------
When I moved my classes hierarchy code from the PHP 4 to the PHP 5 and
renamed costructors from the class names to "__construct", I faced a
segmentation fault.
The constructor calls the parent's constructor.
Parent's constructor calls another method, overloaded in the child's
class.
That overloaded method from the child's class calls the constructor
that calls the parent's constructor again.
But instead of the endless loop I get the segfault.
Reproduce code:
---------------
class A{
function a1(){
echo ' class a ';
}
function a2(){
$this->a1();
}
}
class B extends A {
function a1(){
$this->a2();
}
function __construct(){
parent::a2();
}
}
$a= new B();
Expected result:
----------------
Really, I would like to see the output of " class a " string,
cause it's not convenient to rewrite all occurences of
$this->method() to self::method in the base classes.
But I understand there is a new paradigm of "final" methods now and I
will use it.
I would like to see the endless loop until script execution time
expires:
B::a1() calls A::a2() and vice versa
Actual result:
--------------
Segmentation fault
