I stumbled across a similar problem recently within a member function of a
class template:

//----------------------------
template<class T>
struct A {
  static bool test() {
    static bool value = false;
    if (value)
      return false;
    struct S {
      S() { value = true; }
    };
    static S s;
    return true;
  }
};

int main()
{
  A<int>::test();
}
//----------------------------

"obj\Debug\main.o||In function `A<int>::test()::S::S()':|
main.cpp|8|undefined reference to `value'"

It doesn't occur if A is not a template.

I can confirm the error with gcc 4.7.2 and gcc 4.8.0 20130113 (experimental)
compiled with the flags

-Wall -pedantic-errors
