Defined in:

Overview

Raised when a __builtin_offsetof designator cannot name a byte offset: its type is not a struct/union or is incomplete, a step names no such member, a subscript step applies to a non-array member, or the target is a bit-field (which has no addressable byte offset). It is a NotConstant so every context that already reports a non-constant expression catches it too; detail carries the specific wording for a caller (the generator) that can surface it, over NotConstant's generic message.
