Thanks, I now understand that you either don't see the difference between "indeterminate" and "implementation-defined" in this context or consider it non-essential, so I think I've got your point. > "char" is _special_.

Not mine. I never had problems either with strlen() or with this warning, so was curious why does the warning is such a problem for the kernel. I'm sorry I took your time and haven't got an answer that I entirely agree with. Thank you very much for your explanations anyway. > The warning is CRAP. End of story.
