--- Comment #14 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Francois Dumont <fdum...@gcc.gnu.org>: https://gcc.gnu.org/g:1be57348229666c54954f1e5937cae00e113f7f1 commit r12-9903-g1be57348229666c54954f1e5937cae00e113f7f1 Author: Tim Song <t.canens....@gmail.com> Date: Wed Sep 6 19:31:55 2023 +0200 libstdc++: Force _Hash_node_value_base methods inline to fix abi (PR111050) https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=1b6f0476837205932613ddb2b3429a55c26c409d changed _Hash_node_value_base to no longer derive from _Hash_node_base, which means that its member functions expect _M_storage to be at a different offset. So explosions result if an out-of-line definition is emitted for any of the member functions (say, in a non-optimized build) and the resulting object file is then linked with code built using older version of GCC/libstdc++. libstdc++-v3/ChangeLog: PR libstdc++/111050 * include/bits/hashtable_policy.h (_Hash_node_value_base<>::_M_valptr(), _Hash_node_value_base<>::_M_v()) Add [[__gnu__::__always_inline__]]. (cherry picked from commit 2c1e3544a94c5d7354fad031e1f9731c3ce3af25)
