error[E0658]: casting pointers to integers in constants is unstable (see issue #51910)

error[E0080]: it is undefined behavior to use this value

= note: The rules on what exactly is undefined behavior aren't clear, so this check might be overzealous. Please open an issue on the rust compiler repository if you believe it should not be considered undefined behavior
