No what I am saying is that your code does things which are "undefined" by the C++ standard so the 
compiler is able to do anything (including erasing your hard drive, no gcc will not produce code to do 
that though).  Casting to a different type and then accessing the data inside is declared as undefined 
(there are a few exceptions to that rule, like you access the data via a char pointer and there is no 
aliasing problems, you can cast to a type which adds const or violate and there is no aliasing problems 
but casting between different pointer types and then accessing the data for both of the type is 
undefined).
