libstdc++ might change so that it always implements std::thread, but then have thread startup simply fail. This is being discussed here: https://gcc.gnu.org/pipermail/gcc-patches/2020-November/558736.html This patch pre-emptively changes gdb to handle this scenario. It seemed fine to me to ignore all system errors at thread startup, so that is what this does. gdbsupport/ChangeLog 2020-11-20 Tom Tromey <tromey@adacore.com> * thread-pool.cc (thread_pool::set_thread_count): Ignore system errors.
