           Summary: Casting a class pointer to size_t and back does not

int main()
{
    class C { }
    C c = new C;
    C other = *cast(C *)cast(size_t) &c;
    assert(&other == &c);
    return 0;
}

That assert fires on DMD 2.060

I need this to interface with a C library where I have to pass a pointer as two
ints and then cast them back in a callback.
