I think I found a fix, but I'm not sure if it's correct as I don't know much
about the D runtime. In file object_.d, line 2600:

void clear(T)(ref T obj) if (is(T == struct))
{
-   static if (is(typeof(obj.__dtor())))
-   {
-       obj.__dtor();
-   }
+   typeid(T).destroy( &obj );

    auto buf = (cast(ubyte*) &obj)[0 .. T.sizeof];
    auto init = cast(ubyte[])typeid(T).init();
    if(init.ptr is null) // null ptr means initialize to 0s
        buf[] = 0;
    else
        buf[] = init[];
}

This fixes it for me. You need to modifiy import/object.di as well, because
object_.d doesn't get header'd into object.di, for some reason I don't know.

I might make a pull request, but I'm not 100% this is correct, I would like to
get some feedback.
