[Bug c++/34022] New: Rvalue references and std::forward() broken with built-in types

[eric dot niebler at gmail dot com]

Compile the following program with -std=c++0x. In my understanding, the two
printed addresses should be the same. They are when I invoke foo() with a class
type, but not with built-in types like char.

This is with the latest g++ built from SVN.

#include <cstdio>
#include <utility>

template<typename T> void bar(T &&t)
{
    std::printf("%p\n", &t);
}

template<typename T> void foo(T &&t)
{
    std::printf("%p\n", &t);
    bar(std::forward<T>(t));
}

struct S {};

int main()
{
    foo('a'); // WRONG, prints 2 different addresses
    foo(S()); // OK, prints the same address twice
}
