Yeah, I've got 14.1 over night now, too, and I now see the same :-(.

From a hort look, just replacing sprintf variants with snprintf variants
won't be enough.  Things like make_formatted_string would require
interface changes, for example.

I short, that looks to me like a ton of boring and potentially bug-prone
work.

What do the maintainers think about this?
