--- Comment #14 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:e2babb0540cfa66752214f3f111461e1da4b26ce commit r10-11325-ge2babb0540cfa66752214f3f111461e1da4b26ce Author: Jonathan Wakely <jwak...@redhat.com> Date: Tue Nov 24 12:48:31 2020 +0000 libstdc++: Throw instead of segfaulting in std::thread constructor [PR 67791] This turns a mysterious segfault into an exception with a more useful message. If the exception isn't caught, the user sees this instead of just a segfault: terminate called after throwing an instance of 'std::system_error' what(): Enable multithreading to use std::thread: Operation not permitted Aborted (core dumped) libstdc++-v3/ChangeLog: PR libstdc++/67791 * src/c++11/thread.cc (thread::_M_start_thread(_State_ptr, void (*)())): Check that gthreads is available before calling __gthread_create. (cherry picked from commit 4bbd5d0c5fb2b7527938ad44a6d8a2f2ef8bbe12)
