Issue with casting types

Dear all,
I run into an issue with a simple cast:
https://dpaste.dzfl.pl/8e7f7c545eb1
I have a base class and a class A with inherit from that base
class:
A <- BaseClass
If the base class contains an "alias this", any casting attempt
fails because the "alias this" type gets considered. Thus, I
defined the opCast() to solve this. But now, the program crashes
without any error or exception...
Why does the casting operation consider the "alias this" at all?
I mean: The "alias this" type is int. If I try to cast with to!A,
obviously int does not match A!?
Is there any practical solution? Or should I stop using "alias
this" for my classes? I like the "alias this" concept. But it
caused some issue for me...
Best regards,
Thorsten
