Description:
------------
Adding a property to a class which extends a SplEnum causes a segfault.

Test script:
---------------
class MyEnum extends SplEnum {
    const BLA = 1;
    const BLABLA = 2;
    const BLABLABLA = 3;

    private $someProperty;

}

new MyEnum(1);

Expected result:
----------------
No segfault.

Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.

This affects all SPL Classes. At the moment, the only way around this is to decorate the SPL class, not extend it.

However, this is a serious issue since the classes seem to be built for inheritance. If that's not the case, it should be noted in the documentation.

At least until we have some real types with the current functions built into them.

It should be noted, that SplType functionality is non-existent when you decorate it instead of extending it.

Therefore, this needs to be fixed ASAP please!

Suspending this report as the extension have not had a release for almost 5 years.  Please revive this if the extension once again shows life
