似乎是MS VC2010 lambda表达式中的错误?

静态初始值设定项中使用的lambda表达式的行为 神奇地依赖于lambda体内部初始化的局部变量

int static_1 = 
    [=]() -> int {
      int k_=7;// if this statement presents, the lambda doesn't work (static_1 remains uninitialized)
      return 5;
} ();

int static_2= 
    [=]() -> int {
      //Ok  without variable initializer int k_=7;
      return 5;  
}();

int main() {
  int local= 
      [=]() -> int {
        int k_=7; // Ok with variable initializer  when lambda used in local function context
        return 5;
  } ();

  printf("\n static_1= %d \n static_2= %d \n local= %d", static_1,static_2,local);
}
