A shrunken test case that reproduces same internal error in win32.

void main()
{
    ByLine!()().popFront();
}

struct ByLine()
{
    RefCounted!(ByLineImpl!()) impl;

    void popFront()
    {
        impl._refCounted._store._payload.popFront();
    }
}

private struct ByLineImpl()
{
    char[] line;

    void popFront()
    {
        if (line.length == 0)
        {
            line = null;
        }
        else if (line.length == 0 ? false : line[$-1] == '\n')
        {
            line = line.ptr[0 .. line.length - 1];
        }
    }
}

struct RefCounted(T)
{
    struct RefCountedStore
    {
        private struct Impl
        {
            T _payload;
        }
        private Impl* _store;
    }
    RefCountedStore _refCounted;

    ~this() {}
}
