The destructor doesn't seem to be running

Sorry, I misunderstood you. You can use a RAII object as ketmar 
said:

import std.stdio;
import std.c.stdlib;

struct Test{
    void* ptr;

    ~this(){
        writeln("free: ",&this);
        free(ptr);
    }
}

void main(){
    auto ptr=cast(Test*)malloc(4);
    writeln("create: ",ptr);

    auto test = Test(ptr);  // <-- The dtor of this object will 
free
}

I believe your original understanding was right.I want to have 
HiddenType* be garbage collected and finalized(freed,destructed) 
when no more references to it are found(stack or heap). I could 
use reference counting but it seems inefficient for a program 
rarely collecting and constantly coping.
