It doesn't matter what heap it is on, you are just using a 
pointer here.

Struct pointers in D will automatically dereference with a.x, so 
no need for the * there (in most cases), and assigning it to 
another pointer of course still points to the same object, so it 
will affect both.

If you want a copy, you can use a special method to allocate a 
new one or use auto a = *b; which will copy it to the stack.
