What is actually happening is that the D main function returns.

Then it returns to the OS the exit code.
So it's likely somewhere in there that it's hanging.

I've tried manually reducing the code to find the problem. This 
is what I've got. I'm not sure how to reduce it further.

class Foo {
    ~this() {
        S* next, current;
        next = current = _foo;
        while (next) {
            next = current.next;
            theAllocator.dispose(current);
        }
    }

    void insert(Range)(Range range) {
        foreach (e; range)
            _foo = theAllocator.make!S(_foo);
    }

    S* _foo;

    struct S { S* next; }
}

unittest {
    auto list = new Foo();

    list.insert([1, 2, 3, 4]);
}
