To avoid using uninitialized streams defined in an older libstdc++.so, translation units using the global iostreams should depend on the GLIBCXX_3.4.31 symver. Define std::cin as std::__io::cin and then export it as std::cin@@GLIBCXX_3.4.31 so that references to std::cin bind to the new symver. Also export it as @GLIBCXX_3.4 for backwards compatibility libstdc++-v3/ChangeLog: PR libstdc++/108969 * src/Makefile.am: Move globals_io.cc to here. * src/Makefile.in: Regenerate. * src/c++98/Makefile.am: Remove globals_io.cc from here. * src/c++98/Makefile.in: Regenerate. * src/c++98/globals_io.cc [_GLIBCXX_SYMVER_GNU] (cin): Adjust symbol name and then export with GLIBCXX_3.4.31 symver.
