How to free memory ater use of "new" to allocate it.

[Alain De Vos]

The following program prints two different addresses.
Meaning the new allocates memory until the program dies.
So the means memory leak by default ?


```

import std.stdio:writefln;
import object: destroy;
import core.memory: GC;

void dofun(){
     auto a=new int[1000];
     writefln("%12x",&a);
     destroy(a);
     GC.free(a.ptr);
}

int main(){
     dofun();
     auto b=new int[1000];
     writefln("%12x",&b);
     return 0;
}

```
