The following code compiles on GCC and MSVC but is rejected by Clang:

struct X
{
  const void *p_;

  consteval X()
    : p_{this}
  {
  }
};

static constexpr X x{};

Is Clang correct here? To add to my confusion, if the constructor of the class is marked constexpr rather than consteval, Clang happily accepts the code. I thought for functions constevalimplies constexpr, am I wrong?
