I compile my program using g++ 4.8.5, I find that when my program exits, it
first deconstructs the static member variables of class A, and then
deconstructs a global object of class A. This caused an error in my program.
Could you tell me how can I avoid this problem?Upgrade compiler
version?Modify my code?

my code like this:
class A{
static int var;
~A();                       //A  Destructor depended var
};

int A::var;
A       obj;

var deconstructs before obj
