You freed the CONTENTS, but are printing the CONTAINER.
str_ptr.ptr returns exactly the same thing as str.ptr or
(*str_ptr).ptr, a pointer to the contents. When you write
str_ptr, you print the pointer to the container.
The container isn't moving, it is a stack variable and not
managed by GC. If you want to see changes to the content pointer,
just use it.
string* in D is rarely what you want and I suggest you avoid
using it until you have a strong grasp on the fundamentals of how
arrays and pointers work. You're just confusing yourself by
trying it right now.
Is it's address from 0 of current App memory?
it is the virtual address space, the app doesn't necessarily use
all the possible values.
