Maybe code above works when you enforce an Garbage-collection-run ?
Code below works fine. So you cannot use "new" but must use malloc?

```

import std.stdio:writefln;
import object: destroy;
import core.memory: GC;
import core.stdc.stdlib: malloc,free;


void dofun(){
    auto pa=cast(int *)malloc(1000*int.sizeof);
    writefln("%12x",pa);
    auto a=pa[0..1000];
    free(a.ptr);
}

int main(){
     dofun();
    auto pb=cast(int *)malloc(1000*int.sizeof);
    writefln("%12x",pb);
    auto b=pb[0..1000];
    free(b.ptr);
    return 0;

}

```

Notice how you didn't call `destroy(a)` there. If you did, then 
`free(a)` would be equivalent to `free(null)`, which would do nothing.
