That a construct has no defined meaning does not imply that we must make
every effort to break applications that (erroneously) make use of it.
Would there be any significant drawback for conforming applications
if we made our best to deploy a safety net againt buggy user programs
by not segfaulting in this case?
There are many situations where the system already detects an invalid
pointer and reports it gracefully as an error rather than triggering a
fatal signal.
