I don't think you understand what these terms mean as used in the C
standard.  Either that, or you really believe that an implementation
could document what would happen for every program that returned
garbage instead of a deliberate value, where the garbage is NOT
specified in the program (unlike the case for the part of 4.10.4.3
that you quoted).

Basically, this was specified to cause undefined behavior because
that's exactly what it does.
