An indeterminate value is either an unspecified value or a trap
*representation".  Richard didn't say "trap representation" (I won't
attempt to guess whether that's what he meant.)

A "trap" (not a term used by the standard) usually means that the
program terminates in some unfriendly way -- which might as well be
undefined behavior.
