fuchsia-statically-constructed-objects¶
Warns if global, non-trivial objects with static storage are constructed, unless
the object is statically initialized with a constexpr constructor or has no
explicit constructor.
For example:
class A {};
class B {
public:
  B(int Val) : Val(Val) {}
private:
  int Val;
};
class C {
public:
  C(int Val) : Val(Val) {}
  constexpr C() : Val(0) {}
private:
  int Val;
};
static A a;         // No warning, as there is no explicit constructor
static C c(0);      // No warning, as constructor is constexpr
static B b(0);      // Warning, as constructor is not constexpr
static C c2(0, 1);  // Warning, as constructor is not constexpr
static int i;       // No warning, as it is trivial
extern int get_i();
static C(get_i())   // Warning, as the constructor is dynamically initialized
