seems that I've played too much with »undefined behaviour« in this test;
basically we can not assume ''any'' specific placement of local variables
in a stack frame....
In this test, what I wanted to demonstrate is that the overflow-block can reside
just »anywhere«, and that HeteraoData is just a light-weight front-End and accessor.
However, I can just demonstrate that without totally ''undefined behaviour;''
placement-new can be used to force the storage at a specific location (in the UninitialiesdStorage);
continue to access and use that data after leaving the nested scope is still
kind-of borderline, yet demonstrates that the data itself is just residing in a storage block...
