>It's only tone deaf to people who understand "undefined behavior" as an epithet or as synonymous with giving a license to compilers to screw you over. The term doesn't have either of those meaning to those on the C committee.
It's unfortunate but not surprising that the C committee isn't aware of the problems with the undefined behavior.
In fact, after I started reading WG14 meetings minutes, I completely lost faith that any of the serious problems with the standard will ever get fixed.
