        <pre>This is a bug that <a href="https://reviews.llvm.org/D12689">https://reviews.llvm.org/D12689</a> attempted to address.

The C++11 standard (Section 27.4.1.2) requires that basic streams be
initialized as if an inclusion of <iostream> statically defined an instance of
std::ios_base::Init.

The example given in the changelist:

#include <iostream>

class Foo {
public:
  Foo(int n) {
    std::cout << "Hello World - " << n << std::endl;
  }
};

Foo f(5);

int main() {
  return 0;
}

With the head version of libc++, this program may crash.</pre>
