Huh. You're quite right.
Well, it may have been undefined, but in practice the behaviour was standardised and couldn't be changed without breaking existing code... which is basically C in a nutshell.
- caf 10y agoCode like your example would have been broken by real standard library implementations very early in the piece, because even a forward-copying implementation that does word-at-a-time copies (a straightforward and obvious optimisation with real and significant benefits on many machines of the era) would have broken it.
