    Description

      The following C++11 code crashes with a segmentation fault:

      #include <thread>
      
      int main()
      {
          for (int i = 0; i < 32768; ++i) {
              std::thread t([] {});
              t.join();
          }
          return 0;
      }
      

      Compile with:

      g++ -std=c++0x
      

      It affects i686-4.8.2-release-posix-dwarf-rt_v3-rev3.7z but is fixed in i686-4.8.2-release-posix-dwarf-rt_v3-rev4.7z and later.
