--- Comment #11 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Would it make sense to backport a "transition" version of r13-3707 to the
release branches, one that just adds the static __ioinit object into the
compiled library (without the init_priority attribute, since we only care about
dynamic linking compatibility) and doesn't remove the static object from
<iostream>?
That way, a program compiled with GCC 13 and linked against libstdc++ 12.3
would still work w.r.t. stream initialization. And this library-side
initialization should be safe since the ios_base::Init cdtors are idempotent.
