From: "rs2740 at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug libstdc++/111050] New: [11/12/13/14 Regression] ABI break in _Hash_node_value_base since GCC 11 Date: Thu, 17 Aug 2023 14:40:10 +0000 [thread overview] Message-ID: <bug-111050-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111050 Bug ID: 111050 Summary: [11/12/13/14 Regression] ABI break in _Hash_node_value_base since GCC 11 Product: gcc Version: 13.0 Status: UNCONFIRMED Keywords: ABI Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: rs2740 at gmail dot com Target Milestone: --- 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++.
