There is no library issue here to report. These functions as specified
are consistent with the noexcept guidelines.
If you wish to change them to be guaranteed to be noexcept and thus
prevent implementations that wish
to throw out of them in some debug mode, LEWG is your huckleberry. The
three implementations of these
functions that I can see already make them noexcept anyway.
