class Foo {
    InPlace!Bar inside;
}

class Bar { }

struct InPlace(T) {
        pragma(msg, __traits(classInstanceSize, T));
        private byte[__traits(classInstanceSize, T)] rawData;

        void initializeObject() {
                pragma(msg, __traits(classInstanceSize, T));
        }
}


dmd bug.d
0u
8u


The first one, where the static array is declared, gives 0. The correct value
of 8 is given inside the function.


If you move `class Bar{}` to above Foo's definition, it correctly gives 8 at
both msgs.
