[cfe-users] Error in instantiation of exception specification for vector and string compiling simple code.

[Manu]

Hi,

I get those errors when compiling this simple code:

#include<vector>
#include<string>
struct Bar
{
   Bar(Bar&&) noexcept = default;
   Bar& operator=(Bar&&) noexcept = default;
   std::string name;

};

class Foo
{
public:

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

   Foo()
   {
   }

private:

   std::vector<Bar> 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. I synched
yesterday so I am pretty much up to date.
