Which compiler or language feature requires you to run code on a target?

Examples please.
Note: We are talking about compiler (== toolchain) features and packages
suffering from the toolchain having changed it's behavior. Compilers
never, ever run anything on a target. They are self-contained native
programs and do not/are not able to use any piece of information to be
retrieved at run-time from the target.
