+r[const-eval.const-expr.final-value-provenance]
+The representation of the final value of a [constant][constant initializer] or [static initializer] must only contain bytes with provenance in whole-pointer groups. If a byte has provenance but is not part of an adjacent group of bytes that form an entire pointer, compilation will fail.
+
+> [!NOTE]
+> If a byte in the representation of the final value is uninitialized, then it *may* end up having provenance, which can cause compilation to fail. `rustc` tries (but does not guarantee) to only actually fail if the initializer copies or overwrites parts of a pointer and those bytes appear in the final value.
