Christian Hanné's sources differ from yours in that you are not a troll.
Christian Hanné has a history of posting deliberate misinformation here.
It's not plausible that he's merely mistaken; his lies indicate that he
knows the truth.

The particular nonsense of his that landed him in my killfile a year and
a half ago was:

    Convertion to uintptr_t involves a privilege-check to the page
    addressed. That's not true for conversions to ptrdiff_t or size_t.

(I presume he thinks he's being clever.)
