[Bug c++/29940] New: A variable named _S exists without declaration

["boris dot breidenbach at physik dot uni-erlangen dot de" <gcc-bugzilla@gcc.gnu.org>]

This program compiles:

#include <iostream>

int main()
{
    std::cout << _S << std::endl;

    return 0;

}

If started, it outputs : 8

output of my g++ -v:
