This here adds a nullptr initializer to the InitExprs list.

One reduction appears to fixed in Clang 17: https://godbolt.org/z/Yaae7Tr43 Reduced by me and C-Reduce using assertions build:

template <class _Fn>
struct __conv {
  friend void tag_invoke() noexcept {
    constexpr bool _Nothrow = __nothrow_callable;
    auto __query = [] () noexcept -> __result_t && {
      return [] () noexcept(_Nothrow) {};
    };
  }
};

Clang 16 crash:

<source>:4:31: error: use of undeclared identifier '__nothrow_callable'
    constexpr bool _Nothrow = __nothrow_callable;
                              ^
