--- Comment #5 from Florian Weimer <fw at gcc dot gnu.org> ---
printf is a cancellation point, and can therefore throw. Cancellation is in
POSIX, it's not a glibc extension. I don't think anyone has ever brought up the
need for cancellation handlers that call va_end. I do not think it is possible
to write them.
POSIX should probably specify that va_end is a no-op, or that it is not
required if vfprintf etc. are canceled.
