Static order initialization fiasco, iostream and C++11

According to C++11 specification:

The results of including in a translation unit shall be as if defined an instance of ios_base::Init with static storage duration. Similarly, the entire program shall behave as if there were at least one instance of ios_base::Init with static storage duration

This implies that if my code looks like that:

// A.cpp
#include <iostream>
int foo() {
    cerr << "bar"; 
    return 42;
}

and

// B.cpp
namespace {
unsigned long testuj() {
    int id = foo();
    return id;
}

unsigned long id = testuj();

}

int main() {
     return 0;
}

then I should be safe calling cerr without the risk of a static initialization fiasco.

Unfortunately, the code following code segfaults... Why? I don't think gcc 6.2.1 decided to ignore the C++11 specification.
