Enforcing certain data structure explicit paddings.
Implicit paddings have undefined values in C. We want the eattr blocks to be comparable by memcmp and eattrs settable directly by structrure literals. This check ensures that all paddings in eattr and bval are explicit and therefore zeroed in all literals.
