Stas, care to explain? Uncommenting that will bring back the notice.
And Sjoerd, what did you mean with that comment..?

In _get_zval_cv_lookup(), type is BP_VAR_W, while it should be
BP_VAR_RW for the example code.

Actually, this is a valid problem; the problem described by bug #21008
is a different issue. There seems to be some confusion as to whether it
should be fixed or not, but it's neither a duplicate nor bogus.
Specifically, bug #21008 describes an issue with setting a variable to
a value, where this report describes an issue with updating a variable.
These are two distinct operations, and are handled differently.
More to the point, the following code throws a notice:
<?php
++$n;
?>
That the code described by this bug doesn't is an inconsistency.

Description:
------------
Usually, if you try to do this: ++$num, then thrown notice, that the
"Undefined variable: num". This helps avoid errors.
But if you have class and you're trying to do so ++$this->num num
nowhere and had not previously identified, then the issue no warnings
and notices.
Accidentally deleted in the symbol and received ++$this->nu, and then
climbed into hell knows what mistakes to find this place and correct to
++$this->num took several hours. So I am very concerned about the issue:
how to do so were given notice, if you try to do something with
uninitialized (unknown) variable in the class?
Reproduce code:
---------------
<?php
class A
{ public function __construct()
{ ++$this->num;
}
}
new A();
?>
Expected result:
----------------
Undefined property: A::$num
Actual result:
--------------
empty
