--- Comment #12 from Richard Biener <rguenth at gcc dot gnu.org> --- I wonder why this bug is relevant at all, but even if, then shouldn't the solution be that programs using streams and compiled with GCC 13 require a symbol with a version newer than 6.0.30 (or even not present in the oder DSOs) so the dynamic link will fail?
