module structfail;

auto get(alias fun)() {
    struct Foo {
        size_t data;

        @property
        auto clone() {
            return Foo(data);
        }
    }

    return Foo(0);
}

void main() {
    uint a = 42;
    auto bar = get!(() => a)();

    auto qux = bar.clone;

    import std.stdio;
    writeln("bar context pointer :", (cast(void**) &bar)[1]);
    writeln("qux context pointer :", (cast(void**) &qux)[1]);
}

qux have a garbage context pointer.
