A struct is just a regular local variable, ie. allocated on the stack.
Each time 'Test t;' is executed, the same space is initialized. So it's
overwritten, but it doesn't move.  Except that empty structs might not 
get initialized, even though they have a size of one byte.  You can 
allocate on the heap with 'new' if you want each instance to be unique.

Try this:

Test* t = new Test;
writefln("Pointer: ", cast(int)t);
