gcc warning" 'will be initialized after'

Question

I am getting a lot of these warnings from 3rd party code that I cannot modify. Is there a way to disable this warning or at least disable it for certain areas (like #pragma

Answer 1

Class C {
   int a;
   int b;
   C():b(1),a(2){} //warning, should be C():a(2),b(1)
}

the order is important because if a is initialized before b , and a is depend on b. undefined behavior will appear.
