--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:351ac78e48fa897080cf8bbb71618df9c428ad30 commit r13-9643-g351ac78e48fa897080cf8bbb71618df9c428ad30 Author: Richard Biener <rguent...@suse.de> Date: Mon Nov 6 11:31:40 2023 +0100 libstdc++/112351 - deal with __gthread_once failure during locale init The following makes the C++98 locale init path follow the way the C++11 performs initialization. This way we deal with pthread_once failing, falling back to non-threadsafe initialization which, given we initialize from the library, should be serialized by the dynamic loader already. PR libstdc++/112351 libstdc++-v3/ * src/c++98/locale.cc (locale::facet::_S_initialize_once): Check whether _S_c_locale is already initialized. (locale::facet::_S_get_c_locale): Always perform non-threadsafe init when threadsafe init failed. (cherry picked from commit 7562f089a190953b8ef615b90b7b0520e812a930)
