The Stratus recommendations for structure marking would be a bit harder to defeat.

Here's an excerpt from an old Stratus presentation[0] on writing robust software.

Add TYPE, SIZE, VERSION, and OWNER to data structure

TYPE: Unique number for each different structure

SIZE: in bytes

VERSION: Changed whenever structure declaration changes

OWNER: Unique ID of owner, must be independent of structure contents; can be UID, least significant bits of clock, etc.
