Order of evaluation of elements in list-initialization

Question

In the other topic, @Dietmar gave this solution:

template 
std::tuple parse(std::istream& in) 
{
    return std::tuple&l

^{Answering my own question. Deleting the question would not be a good idea, as someone might have the same question in the future.}

Yes. It is a bug in the GCC compiler.
