I think it is just that sanitizer didn't caught up to the C++20 standard where
constexpr was relaxed to allow uninitialized variables.
Constant initialization is applied only when class constructor in constexpr,
and only since C++20 'A' class has constexpr constructor.

Proof, following compiles only since C++20:
struct A {
  int value;
  constexpr A() = default;
};
