#include <iostream>
using namespace std;
struct A {
int x;
A(){ x = 17; }
};
template<class T>
struct B {
static A a;
int x;
B(){ x = a.x; }
};
template<class T>
A B<T>::a;
B<int> b;
int main()
{
cout << b.x << ' ' << b.a.x << endl;
}
The abould code should initialize B<int>::a before the global static b,
resulting in '17 17'. However, the actual output is '0 17'.

Subject: Re: wrong order of static initialization
10112 is a mess.
The original testcase there does not fail anymore. This makes it
very difficult for bug submitters to recognize it as a duplicate,
resulting in lots of wasted bug reports.

Then let's keep this one open. Whoever fixes it should double-check
the other one as well.

Well this is undefined which is why this is a dup of bug 10112 and nothing more.

Even though the testcase in PR 10112 is fixed (or is it), the problem is the same, the order in this case
is undefined.

------- Comment #6 from jason at gcc dot gnu dot org 2009-11-08 23:24 -------
14.7.4.1 [temp.point] says:
...the point of instantiation for such a specialization immediately follows the
namespace scope declaration or definition that refers to the specialization.
So, the point of instantiation for B<int>::B(), and thus for B<int>::a, is
*after* the declaration of b, and therefore there's no reason to expect
B<int>::a to be initialized before b.
If you need B<int>::a to be initialized before b, you can provide an explicit
instantiation:
template A B<int>::a;
B<int> b;
