--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> --- r14-739-gc62e945492afbb incorrectly added them to GLIBCXX_3.4.32 which should have been frozen after 13.1 but it looks like I thought it was a new version for 13.2/14.0 Then I must have thought 13.2 and 14.0 were both using that new version, they should both have those new symbols.
