I don't claim that it is an error in the documentation, or the
compiler or the implementation. The meaning of 'undefined' is
precisely that it has not been defined. In this context it means, more
specifically, that it has not been defined in the language report.
Any other definition or 'interpretation' is just Humpty-Dumptying.

The predictability or otherwise of the result is irrelevant. Indeed,
programmers are explicitly warned not to use undefined but predictable
results because they may change from one implementation to another -
this is what information hiding, encapsulation and scalars are for.
