I'm curious as to why returning a reference to a local inside an inline
function isn't (apparently) allowed. eg:

#include <iostream>
#include <string>

using namespace std;

inline string &func()
{
        string s = "hello";
        return s;
}



int main()
{
        cout << func() << endl;
        return 0;
}

This causes a compilation warning with clang and when run prints out garbage
as you'd expect if it were a non inline. However surely if the function is
truly inline it should work. Are locals for inlines temporaries created on the 
heap instead of being stored on the same stack as the calling function locals?
