Application Security Testing: An Integral Part of DevOps

Global Anonymous Unions Have to be Declared Static

An anonymous union declared in a named namespace or in the global namespace has to be explicitly declared static:
  static union { int num; char *pc; }; //anonymous union in global namespace
  namespace NS 
    static union { double d; bool b;}; //anonymous union in a named namespace
  int main()
    NS::d = 0.0;
    num = 5;
    pc = "str";
