           Summary: dip25 wrong escaping reference to this

           Version: D2
          Hardware: All
                OS: All

when compiling with -dip25

struct S(things...)
{
    ref foo(newThings...)()
    {
        alias NewT = S!(things, newThings);
        return *(() => cast(NewT*)&this)();
    }
}

void main()
{
    S!float s;
    auto s1 = s.foo!(int); //OK
    auto s2 = s.foo!(); //Error escaping reference to this
}

worked fine in 2.071.2-b1, fails with current git HEAD
